+.SH "WIDGET-SPECIFIC OPTIONS"
+.OP \-autoclear autoClear AutoClear
+A boolean value which specifies whether the first keypress in a cell will
+delete whatever text was previously there. Defaults to 0.
+.OP \-bordercursor borderCursor Cursor
+Specifies the name of the cursor to show when over borders, a visual
+indication that interactive resizing is allowed (it is thus affect by
+the value of \-resizeborders). Defaults to \fIcrosshair\fR.
+.OP "\-borderwidth or \-bd" borderWidth BorderWidth
+Specifies a non-negative pixel value or list of values indicating the width
+of the 3-D border to draw on interior table cells (if such a border is
+being drawn; the \fBrelief\fR option typically determines this). If one
+value is specified, a rectangle of this width will be drawn. If two values
+are specified, then only the left and right edges of the cell will have
+borders. If four values are specified, then the values correspond to the
+{left right top bottom} edges. This can be overridden by the a tag's
+borderwidth option. It can also be affected by the defined
+\fB\-drawmode\fR for the table. Each value in the list must have one of
+the forms acceptable to \fBTk_GetPixels\fR.
+.OP "\-browsecommand or \-browsecmd" browseCommand BrowseCommand
+Specifies a command which will be evaluated anytime the active cell changes.
+It uses the %\-substition model described in COMMAND SUBSTITUTION below.
+Any changes to the active cell while the command is running are ignored to
+prevent recursion.
+.OP \-cache cache Cache
+A boolean value that specifies whether an internal cache of the table
+contents should be kept. This greatly enhances speed performance when used
+with \fB\-command\fR but uses extra memory. Can maintain state when both
+\fB\-command\fR and \fB\-variable\fR are empty. The cache is automatically
+flushed whenever the value of \fB\-cache\fR or \fB\-variable\fR changes,
+otherwise you have to explicitly call \fBclear\fR on it. Defaults to off.
+.OP \-colorigin colOrigin Origin
+Specifies what column index to interpret as the leftmost column in the table.
+This value is used for user indices in the table. Defaults to 0.
+.OP \-cols cols Cols
+Number of cols in the table. Defaults to 10.
+.OP \-colseparator colSeparator Separator
+Specifies a separator character that will be interpreted as the column
+separator when cutting or pasting data in a table. By default, columns
+are separated as elements of a tcl list.
+.OP \-colstretchmode colStretchMode StretchMode
+Specifies one of the following stretch modes for columns to fill extra
+allocated window space:
+.RS
+.TP
+\fBnone\fR
+Columns will not stretch to fill the assigned window space. If the columns
+are too narrow, there will be a blank space at the right of the table. This
+is the default.
+.TP
+\fBunset\fR
+Only columns that do not have a specific width set will be stretched.
+.TP
+\fBall\fR
+All columns will be stretched by the same number of pixels to fill the
+window space allocated to the table. This mode can interfere with
+interactive border resizing which tries to force column width.
+.TP
+\fBlast\fR
+The last column will be stretched
+to fill the window space allocated to the table.
+.TP
+\fBfill\fR (only valid for \fB\-rowstretch\fR currently)
+The table will get more or less columns according to the window
+space allocated to the table. This mode has numerous quirks and
+may disappear in the future.
+.RE
+.OP \-coltagcommand colTagCommand TagCommand
+Provides the name of a procedure that will be evaluated by the widget to
+determine the tag to be used for a given column. When displaying a cell,
+the table widget will first check to see if a tag has been defined using the
+\fBtag col\fR widget method. If no tag is found, it will evaluate the named
+procedure passing the column number in question as the sole argument. The
+procedure is expected to return the name of a tag to use, or a null string.
+Errors occurring during the evaluation of the procedure, or the return of an
+invalid tag name are silently ignored.
+.OP \-colwidth colWidth ColWidth
+Default column width, interpreted as characters in the default font when
+the number is positive, or pixels if it is negative. Defaults to 10.
+.OP \-command command Command
+Specified a command to use as a procedural interface to cell values.
+If \fB\-usecommand\fR is true, this command will be used instead of any
+reference to the \fB\-variable\fR array. When retrieving cell values,
+the return value of the command is used as the value for the cell.
+It uses the %\-substition model described in COMMAND SUBSTITUTION below.
+.OP \-drawmode drawMode DrawMode
+Sets the table drawing mode to one of the following options:
+.RS
+.TP
+\fBslow\fR
+The table is drawn to an offscreen pixmap using the Tk bordering functions
+(double-buffering). This means there will be no flashing, but this mode is
+slow for larger tables.
+.TP
+\fBcompatible\fR
+The table is drawn directly to the screen using the Tk border functions.
+It is faster, but the screen may flash on update. This is the default.
+.TP
+\fBfast\fR
+The table is drawn directly to the screen and the borders are done with
+fast X calls, so they are always one pixel wide only. As a side effect, it
+restricts \fB\-borderwidth\fR to a range of 0 or 1. This mode provides
+best performance for large tables, but can flash on redraw and is not 100%
+Tk compatible on the border mode.
+.TP
+\fBsingle\fR
+The table is drawn to the screen as in fast mode, but only single pixel
+lines are drawn (not square borders).
+.RE
+.OP \-ellipsis ellipsis Ellipsis
+This specifies a string to display at the end of a line that would be
+clipped by its cell, like ``...''. An ellipsis will be displayed only
+on non-wrapping, non-multiline cells that would be clipped. The ellipsis
+will display on the left for east anchored cells, otherwise it displays
+on the right.
+Defaults to "" (no ellipsis).
+.OP \-flashmode flashMode FlashMode
+A boolean value which specifies whether cells should flash when their value
+changes. The table tag \fBflash\fR will be applied to these cells for the
+duration specified by \fB\-flashtime\fR. Defaults to 0.
+.OP \-flashtime flashTime FlashTime
+The amount of time, in 1/4 second increments, for which a cell should flash
+when its value has changed. \fB\-flashmode\fR must be on. Defaults to 2.
+.OP \-height height Height
+Specifies the desired height for the window, in rows.
+If zero or less, then the desired height for the window is made just
+large enough to hold all the rows in the table. The height can be
+further limited by \fB\-maxheight\fR.
+.OP \-invertselected invertSelected InvertSelected
+Specifies whether the foreground and background of an item should simply
+have their values swapped instead of merging the \fIsel\fR tag options
+when the cell is selected. Defaults to 0 (merge \fIsel\fR tag).
+.OP \-ipadx ipadX Pad
+A pixel value specifying the internal offset X padding for text in a cell.
+This value does not grow the size of the cell, it just causes the text to
+be drawn further from the cell border. It only affects one side (depending
+on anchor). Defaults to 0. See \fB\-padx\fR for an alternate padding
+style.
+.OP \-ipady ipadY Pad
+A pixel value specifying the internal offset Y padding for text in a cell.
+This value does not grow the size of the cell, it just causes the text to
+be drawn further from the cell border. It only affects one side (depending
+on anchor). Defaults to 0. See \fB\-pady\fR for an alternate padding
+style.
+.OP \-justify justify Justify
+How to justify multi\-line text in a cell.
+It must be one of \fBleft\fR, \fBright\fR, or \fBcenter\fR.
+Defaults to left.
+.OP \-maxheight maxHeight MaxHeight
+The max height in pixels that the window will request. Defaults to 600.
+.OP \-maxwidth maxWidth MaxWidth
+The max width in pixels that the window will request. Defaults to 800.
+.OP \-multiline multiline Multiline
+Specifies the default setting for the multiline tag option. Defaults to 1.
+.OP \-padx padX Pad
+A pixel value specifying the offset X padding for a cell. This value
+causes the default size of the cell to increase by two times the value (one
+for each side), unless a specific pixel size is chosen for the cell with
+the \fBwidth\fR command. This will force an empty area on the left and
+right of each cell edge. This padding affects all types of data in the
+cell. Defaults to 0. See \fB\-ipadx\fR for an alternate padding style.
+.OP \-pady padY Pad
+A pixel value specifying the offset Y padding for a cell. This value
+causes the default size of the cell to increase by two times the value (one
+for each side), unless a specific pixel size is chosen for the cell with
+the \fBheight\fR command. This will force an empty area on the top and
+bottom of each cell edge. This padding affects all types of data in the
+cell. Defaults to 0. See \fB\-ipadx\fR for an alternate padding style.
+.OP \-resizeborders resizeBorders ResizeBorders
+Specifies what kind of interactive border resizing to allow, must be one of
+row, col, both (default) or none.
+.OP \-rowheight rowHeight RowHeight
+Default row height, interpreted as lines in the default font when
+the number is positive, or pixels if it is negative. Defaults to 1.
+.OP \-roworigin rowOrigin Origin
+Specifies what row index to interpret as the topmost row in the table.
+This value is used for user indices in the table. Defaults to 0.
+.OP \-rows rows Rows
+Number of rows in the table. Defaults to 10.
+.OP \-rowseparator rowSeparator Separator
+Specifies a separator character that will be interpreted as the row
+separator when cutting or pasting data in a table. By default, rows
+are separated as tcl lists.
+.OP \-rowstretchmode rowStretchMode StretchMode
+Specifies the stretch modes for rows to fill extra
+allocated window space. See \fB\-colstretchmode\fR for valid options.
+.OP \-rowtagcommand rowTagCommand TagCommand
+Provides the name of a procedure that can evaluated by the widget to
+determine the tag to be used for a given row. The procedure must be
+defined by the user to accept a single argument (the row number), and
+return a tag name or null string. This operates in a similar manner as
+\fB\-coltagcommand\fR, except that it applies to row tags.
+.OP "\-selectioncommand or \-selcmd" selectionCommand SelectionCommand
+Specifies a command to evaluate when the selection is retrieved from a
+table via the selection mechanism (ie: evaluating ``\fBselection get\fR'').
+The return value from this command will become the string passed on by the
+selection mechanism. It uses the %\-substition model described in COMMAND
+SUBSTITUTION below. If an error occurs, a Tcl background error is
+generated and nothing is returned.
+.OP \-selectmode selectMode SelectMode
+Specifies one of several styles for manipulating the selection. The value
+of the option may be arbitrary, but the default bindings expect it to be
+either \fBsingle\fR, \fBbrowse\fR, \fBmultiple\fR, or \fBextended\fR; the
+default value is \fBbrowse\fR. These styles are like those for the Tk
+listbox, except expanded for 2 dimensions.
+.OP \-selecttitle selectTitles SelectTitles
+Specifies whether title cells should be allowed in the selection.
+Defaults to 0 (disallowed).
+.OP \-selecttype selectType SelectType
+Specifies one of several types of selection for the table. The value of the
+option may be one of \fBrow\fR, \fBcol\fR, \fBcell\fR, or \fBboth\fR
+(meaning \fBrow && col\fR); the default value is \fBcell\fR. These types
+define whether an entire row/col is affected when a cell's selection is
+changed (set or clear).
+.OP \-sparsearray sparseArray SparseArray
+A boolean value that specifies whether an associated Tcl array should be
+kept as a sparse array (1, the default) or as a full array (0). If true,
+then cell values that are empty will be deleted from the array (taking
+less memory). If false, then all values in the array will be maintained.
+.OP \-state state State
+Specifies one of two states for the entry: \fBnormal\fR or \fBdisabled\fR.
+If the table is disabled then the value may not be changed using widget
+commands and no insertion cursor will be displayed, even if the input focus
+is in the widget. Also, all insert or delete methods will be ignored.
+Defaults to \fBnormal\fR.
+.OP \-titlecols titleCols TitleCols
+Number of columns to use as a title area. Defaults to 0.
+.OP \-titlerows titleRows TitleRows
+Number of rows to use as a title area. Defaults to 0.
+.OP \-usecommand useCommand UseCommand
+A boolean value which specifies whether to use the \fBcommand\fR option.
+This value sets itself to zero if \fBcommand\fR is used and returns an error.
+Defaults to 1 (will use \fBcommand\fR if specified).
+.OP \-validate validate Validate
+A boolean specifying whether validation should occur for the active buffer.
+Defaults to 0.
+.OP "\-validatecommand or \-vcmd" validateCommand ValidateCommand
+Specifies a command to execute when the active cell is edited. This command
+is expected to return a Tcl boolean. If it returns true, then it is assumed
+the new value is OK, otherwise the new value is rejected (the edition will
+not take place). Errors in this command are handled in the background. It
+uses the %\-substition model described in COMMAND SUBSTITUTION below.
+.OP \-variable variable Variable
+Global Tcl array variable to attach to the table's C array. It will be
+created if it doesn't already exist or is a simple variable. Keys used by
+the table in the array are of the form \fIrow\fR,\fIcol\fR for cells and
+the special key \fIactive\fR which contains the value of the active cell
+buffer. The Tcl array is managed as a sparse array (the table does not
+require that all valid indices have values). No stored value for an index is
+equivalent to the empty string, and clearing a cell will remove that index
+from the Tcl array, unless the \fB\-sparsearray\fR options is set to 0.
+.OP \-width width Width
+Specifies the desired width for the window, in columns.
+If zero or less, then the desired width for the window is made just
+large enough to hold all the columns in the table. The width can be
+further limited by \fB\-maxwidth\fR.
+.OP \-wrap wrap Wrap
+Specifies the default wrap value for tags. Defaults to 0.
+.BE
+
+.SH DESCRIPTION
+.PP
+The \fBtable\fR command creates a 2\-dimensional grid of cells. The table
+can use a Tcl array variable or Tcl command for data storage and retrieval,
+as well as optionally cache data in memory for speed. One of these data
+sources \fImust\fR be configured before any data is retained by the table.
+The widget has an active cell, the contents of which can be edited (when
+the state is normal). The widget supports a default style for the cells
+and also multiple \fItags\fR, which can be used to change the style of a
+row, column or cell (see TAGS for details). A cell \fIflash\fR can be set
+up so that changed cells will change color for a specified amount of time
+("blink"). Cells can have embedded images or windows, as described in
+TAGS and "EMBEDDED WINDOWS" respectively.
+.PP
+One or more cells may be selected as described below. If a table is
+exporting its selection (see \fB\-exportselection\fR option), then it will
+observe the standard X11 protocols for handling the selection. See THE
+SELECTION for details.
+.PP
+It is not necessary for all the cells to be displayed in the table window at
+once; commands described below may be used to change the view in the window.
+Tables allow scrolling in both directions using the standard
+\fB\-xscrollcommand\fR and \fB\-yscrollcommand\fR options. They also support
+scanning, as described below.
+.PP
+In order to obtain good performance, the table widget supports multiple
+drawing modes, two of which are fully Tk compatible.
+
+.SH "INITIALIZATION"
+.PP
+When the \fBtable\fR command is loaded into an interpreter, a built-in
+Tcl command, \fBtkTableInit\fR, is evaluated. This will search for the
+appropriate table binding init file to load. The directories searched
+are those in \fI$tcl_pkgPath\fR, both with Tktable(version) appended and
+without, \fI$tk_library\fR and \fI[pwd]\fR (the current directory). You
+can also define an \fI$env(TK_TABLE_LIBRARY)\fR to head this search list.
+By default, the file searched for is called \fBtkTable.tcl\fR, but this
+can be overridden by setting \fI$env(TK_TABLE_LIBRARY_FILE)\fR.
+.PP
+This entire init script can be overridden by providing your own
+\fBtkTableInit\fR procedure before the library is loaded. Otherwise, the
+aforementioned \fIenv(TK_TABLE_LIBRARY)\fR variable will be set with the
+directory in which \fI$env(TK_TABLE_LIBRARY_FILE)\fR was found.
+
+.SH "INDICES"
+.PP
+Many of the widget commands for tables take one or more indices as arguments.
+An index specifies a particular cell of the table, in any of
+the following ways:
+.TP 12
+\fInumber,number\fR
+Specifies the cell as a numerical index of row,col which corresponds to the
+index of the associated Tcl array, where \fB\-roworigin,\-colorigin\fR
+corresponds to the first cell in the table (0,0 by default). The values
+for row and column will be constrained to actual values in the table,
+which means a valid cell is always found.
+.TP 12
+\fBactive\fR
+Indicates the cell that has the location cursor.
+It is specified with the \fBactivate\fR widget command.
+.TP 12
+\fBanchor\fR
+Indicates the anchor point for the selection, which is set with the
+\fBselection anchor\fR widget command.
+.TP 12
+\fBbottomright\fR
+Indicates the bottom\-rightmost cell visible in the table.
+.TP 12
+\fBend\fR
+Indicates the bottom right cell of the table.
+.TP 12
+\fBorigin\fR
+Indicates the top\-leftmost editable cell of the table, not necessarily
+in the display. This takes into account the user specified origin and
+title area.
+.TP 12
+\fBtopleft\fR
+Indicates the top\-leftmost editable cell visible in the table (this

+.SH TAGS
+.PP
+A tag is a textual string that is associated with zero or more rows,
+columns or cells in a table. Tags may contain arbitrary characters, but it
+is probably best to avoid using names which look like indices to reduce
+coding confusion. A tag can apply to an entire row or column, or just a
+single cell. There are several permanent tags in each table that can be
+configured by the user and will determine the attributes for special cells:
+.RS
+.TP 10
+\fBactive\fR
+This tag is given to the \fIactive\fR cell
+.TP 10
+\fBflash\fR
+If flash mode is on, this tag is given to any recently
+edited cells.
+.TP 10
+\fBsel\fR
+This tag is given to any selected cells.
+.TP 10
+\fBtitle\fR
+This tag is given to any cells in the title rows and columns. This
+tag has \fB\-state\fR \fIdisabled\fR by default.
+.RE
+.PP
+Tags control the way cells are displayed on the screen. Where appropriate,
+the default for displaying cells is determined by the options for the table
+widget. However, display options may be associated with individual tags
+using the ``\fIpathName \fBtag configure\fR'' widget command. If a cell,
+row or column has been tagged, then the display options associated with the
+tag override the default display style. The following options are
+currently supported for tags:
+.RS
+.TP
+\fB\-anchor\fR \fIanchor\fR
+Anchor for item in the cell space.
+.TP
+\fB\-background\fR or \fB\-bg\fR \fIcolor\fR
+Background color of the cell.
+.TP
+\fB\-borderwidth\fR or \fB\-bd\fR \fIpixelList\fR
+Borderwidth of the cell, of the same format for the table, but may also
+be empty to inherit the default table borderwidth value (the default).
+.TP
+\fB\-ellipsis\fR \fIstring\fR
+String to display at the end of a line that would be clipped by its cell,
+like ``...''. An ellipsis will be displayed only
+on non-wrapping, non-multiline cells that would be clipped. The ellipsis
+will display on the left for east anchored cells, otherwise it displays
+on the right.
+.TP
+\fB\-font\fR \fIfontName\fR
+Font for text in the cell.
+.TP
+\fB\-foreground\fR or \fB\-fg\fR \fIcolor\fR
+Foreground color of the cell.
+.TP
+\fB\-justify\fR \fIjustify\fR
+How to justify multi\-line text in a cell.
+It must be one of \fBleft\fR, \fBright\fR, or \fBcenter\fR.
+.TP
+\fB\-image\fR \fIimageName\fR
+An image to display in the cell instead of text.
+.TP
+\fB\-multiline\fR \fIboolean\fR
+Whether to display text with newlines on multiple lines.
+.TP
+\fB\-relief\fR \fIrelief\fR
+The relief for the cell. May be the empty string to cause this tag to
+not disturb the value.
+.TP
+\fB\-showtext\fR \fIboolean\fR
+Whether to show the text over an image.
+.TP
+\fB\-state\fR \fIstate\fR
+The state of the cell, to allow for certain cells to be disabled.
+This prevents the cell from being edited by the \fIinsert\fR or \fIdelete\fR
+methods, but a direct \fIset\fR will not be prevented.
+.TP
+\fB\-wrap\fR \fIboolean\fR
+Whether characters should wrap in a cell that is not wide enough.
+.RE
+.PP
+A priority order is defined among tags based on creation order (first
+created tag has highest default priority), and this order is used in
+implementing some of the tag\-related functions described below. When a cell
+is displayed, its properties are determined by the tags which are assigned
+to it. The priority of a tag can be modified by the ``\fIpathName \fBtag
+lower\fR'' and ``\fIpathName \fBtag raise\fR'' widget commands.
+.PP
+If a cell has several tags associated with it that define the same display
+options (eg - a \fBtitle\fR cell with specific \fBrow\fR and \fBcell\fR
+tags), then the options of the highest priority tag are used. If a
+particular display option hasn't been specified for a particular tag, or if
+it is specified as an empty string, then that option will not be used; the
+next\-highest\-priority tag's option will be used instead. If no tag
+specifies a particular display option, then the default style for the
+widget will be used.
+.PP
+Images are used for display purposes only. Editing in that cell will still
+be enabled and any querying of the cell will show the text value of the cell,
+regardless of the value of \fB\-showtext\fR.
+
+.SH "EMBEDDED WINDOWS"
+.PP
+There may be any number of embedded windows in a table widget (one per
+cell), and any widget may be used as an embedded window (subject to the
+usual rules for geometry management, which require the table window to be
+the parent of the embedded window or a descendant of its parent). The
+embedded window's position on the screen will be updated as the table is
+modified or scrolled, and it will be mapped and unmapped as it moves into
+and out of the visible area of the table widget. Each embedded window
+occupies one cell's worth of space in the table widget, and it is referred
+to by the index of the cell in the table. Windows associated with the
+table widget are destroyed when the table widget is destroyed.
+.PP
+Windows are used for display purposes only. A value still exists for that
+cell, but will not be shown unless the window is deleted in some way. If
+the window is destroyed or lost by the table widget to another geometry
+manager, then any data associated with it is lost (the cell it occupied
+will no longer appear in \fBwindow names\fR).
+.PP
+When an embedded window is added to a table widget with the window
+configure widget command, several configuration options may be associated
+with it. These options may be modified with later calls to the window
+configure widget command. The following options are currently supported:
+.RS
+.TP
+\fB\-create \fIscript\fR
+NOT CURRENTLY SUPPORTED. Specifies a Tcl script that may be evaluated to
+create the window for the annotation. If no \-window option has been
+specified for this cell then this script will be evaluated when the
+cell is about to be displayed on the screen. Script must create a
+window for the cell and return the name of that window as its result.
+If the cell's window should ever be deleted, the script will be evaluated
+again the next time the cell is displayed.
+.TP
+\fB\-background\fR or \fB\-bg\fR \fIcolor\fR
+Background color of the cell. If not
+specified, it uses the table's default background.
+.TP
+\fB\-borderwidth\fR or \fB\-bd\fR \fIpixelList\fR
+Borderwidth of the cell, of the same format for the table, but may also
+be empty to inherit the default table borderwidth value (the default).
+.TP
+\fB\-padx \fIpixels\fR
+As defined in the Tk options man page.
+.TP
+\fB\-pady \fIpixels\fR
+As defined in the Tk options man page.
+.TP
+\fB\-relief \fIrelief\fR
+The relief to use for the cell in which the window lies. If not
+specified, it uses the table's default relief.
+.TP
+\fB\-sticky \fIsticky\fR
+Stickiness of the window inside the cell, as defined by the \fBgrid\fR command.
+.TP
+\fB\-window \fIpathName\fR
+Specifies the name of a window (widget) to display in the annotation. It
+must exist before being specified here. When an empty string is specified,
+if a window was displayed it will cease to be managed by the table widget.
+.RE
+
+.SH "THE SELECTION"
+.PP
+Table selections are available as type STRING. By default, the value of
+the selection will be the values of the selected cells in nested Tcl list
+form where each row is a list and each column is an element of a row list.
+You can change the way this value is interpreted by setting the
+\fB\-rowseparator\fR and \fB\-colseparator\fR options. For example,
+default Excel format would be to set \fB\-rowseparator\fR to '\\n' and
+\fB\-colseparator\fR to '\\t'. Changing these values affects both how the
+table sends out the selection and reads in pasted data, ensuring that the
+table should always be able to cut and paste to itself. It is possible to
+change how pastes are handled by editing the table library procedure
+\fBtk_tablePasteHandler\fR. This might be necessary if
+\fB\-selectioncommand\fR is set.
+
+.SH "ROW/COL SPANNING"
+.PP
+Individual cells can span multiple rows and/or columns. This is done
+via the \fBspans\fR command (see below for exact arguments). Cells in
+the title area that span are not permitted to span beyond the title area,
+and will be constrained accordingly. If the title area shrinks during a
+configure, sanity checking will occur to ensure the above. You may set
+spans on regular cells that extend beyond the defined row/col area. These
+spans will not be constrained, so that when the defined row/col area
+expands, the span will expand with it.
+.PP
+When setting a span, checks are made as to whether the span would overlap
+an already spanning or hidden cell. This is an error and it not allowed.
+Spans can affect the overall speed of table drawing, although not
+significantly. If spans are not used, then there is no performance loss.
+.PP
+Cells \fIhidden\fR by spanning cells still have valid data. This will
+be seen during cut and paste operations that involve hidden cells, or
+through direct access by a command like \fBget\fR or \fBset\fR.
+.PP
+The drawing properties of spanning cells apply to only the visual area
+of the cell. For example, if a cell is center justified over 5 columns,
+then when viewing any portion of those columns, it will appear centered
+in the visible area. The non-visible column area will not be considered
+in the centering calculations.
+
+.SH "COMMAND SUBSTITUTION"
+.PP
+
+The various option based commands that the table supports all support the
+familiar Tk %\-substitution model (see \fBbind\fR for more details). The
+following %\-sequences are recognized and substituted by the table widget:
+.TP 5
+\fB%c\fR
+For \fBSelectionCommand\fR, it is the maximum number of columns in any
+row in the selection. Otherwise it is the column of the triggered cell.
+.TP 5
+\fB%C\fR
+A convenience substitution for \fI%r\fR,\fI%c\fR.
+.TP 5
+\fB%i\fR
+For \fBSelectionCommand\fR, it is the total number of cells in the selection.
+For \fBCommand\fR, it is 0 for a read (get) and 1 for a write (set).
+Otherwise it is the current cursor position in the cell.
+.TP 5
+\fB%r\fR
+For \fBSelectionCommand\fR, it is the number of rows in the selection.
+Otherwise it is the row of the triggered cell.
+.TP 5
+\fB%s\fR
+For \fBValidateCommand\fR, it is the current value of the cell being validated.
+For \fBSelectionCommand\fR, it is the default value of the selection.
+For \fBBrowseCommand\fR, it is the index of the last active cell.
+For \fBCommand\fR, it is empty for reads (get) and the current value of the
+cell for writes (set).
+.TP 5
+\fB%S\fR
+For \fBValidateCommand\fR, it is the potential new value of the cell
+being validated.
+For \fBBrowseCommand\fR, it is the index of the new active cell.
+.TP 5
+\fB%W\fR
+The pathname to the window for which the command was generated.

+.SH "WIDGET COMMAND"
+.PP
+The \fBtable\fR command creates a new Tcl command whose
+name is \fIpathName\fR. This command may be used to invoke various
+operations on the widget. It has the following general form:
+.CS
+\fIpathName option \fR?\fIarg arg ...\fR?
+.CE
+\fIOption\fR and the \fIarg\fRs
+determine the exact behavior of the command.
+.PP
+The following commands are possible for \fBtable\fR widgets:
+.TP
+\fIpathName \fBactivate\fR \fIindex\fR
+Sets the active cell to the one indicated by \fIindex\fR.
+.TP
+\fIpathName \fBbbox\fR \fIfirst\fR ?\fIlast\fR?
+It returns the bounding box for the specified cell (range) as a 4\-tuple of
+x, y, width and height in pixels. It clips the box to the visible portion,
+if any, otherwise an empty string is returned.
+.TP
+\fIpathName \fBborder\fR \fIoption args\fR
+This command is a voodoo hack to implement border sizing for tables.
+This is normally called through bindings, with the following as valid
+options:
+.RS
+.TP
+\fIpathName \fBborder mark\fR \fIx y\fR ?\fIrow|col\fR?
+Records \fIx\fR and \fIy\fR and the row and/or column border under that
+point in the table window, if any; used in conjunction with later \fBborder
+dragto\fR commands. Typically this command is associated with a mouse
+button press in the widget. If \fIrow\fR or \fIcol\fR is not specified, it
+returns a tuple of both border indices (an empty item means no border).
+Otherwise, just the specified item is returned.
+.TP
+\fIpathName \fBborder dragto\fR \fIx y\fR
+This command computes the difference between its \fIx\fR and \fIy\fR
+arguments and the \fIx\fR and \fIy\fR arguments to the last \fBborder
+mark\fR command for the widget. It then adjusts the previously marked
+border by the difference. This command is typically associated with mouse
+motion events in the widget, to produce the effect of interactive border
+resizing.

+.TP
+\fIpathName \fBclear\fR \fIoption\fR ?\fIfirst\fR? ?\fIlast\fR?
+This command is a convenience routine to clear certain state information
+managed by the table. \fIfirst\fR and \fIlast\fR represent valid table
+indices. If neither are specified, then the command operates on the
+whole table. The following options are recognized:
+.RS
+.TP
+\fIpathName \fBclear cache\fR ?\fIfirst\fR? ?\fIlast\fR?
+Clears the specified section of the cache, if the table has been
+keeping one.
+.TP
+\fIpathName \fBclear sizes\fR ?\fIfirst\fR? ?\fIlast\fR?
+Clears the specified row and column areas of specific height/width
+dimensions. When just one index is specified, for example \fB2,0\fR,
+that is interpreted as row 2 \fBand\fR column 0.
+.TP
+\fIpathName \fBclear tags\fR ?\fIfirst\fR? ?\fIlast\fR?
+Clears the specified area of tags (all row, column and cell tags).

+.TP
+\fIpathName \fBconfigure\fR ?\fIoption\fR? ?\fIvalue option value ...\fR?
+Query or modify the configuration options of the widget.
+If no \fIoption\fR is specified, returns a list describing all of
+the available options for \fIpathName\fR (see \fBTk_ConfigureInfo\fR for
+information on the format of this list). If \fIoption\fR is specified
+with no \fIvalue\fR, then the command returns a list describing the
+one named option (this list will be identical to the corresponding
+sublist of the value returned if no \fIoption\fR is specified). If
+one or more \fIoption\-value\fR pairs are specified, then the command
+modifies the given widget option(s) to have the given value(s); in

+\fIindex\fR will be constrained to the limits of the tables. If
+\fIcount\fR is negative, it deletes cols to the left. Otherwise it deletes
+cols to the right. \fIcount\fR defaults to 1 (meaning just the column
+specified). At the moment, spans are
+not adjusted with this action. Optional switches are:

+.SH "DEFAULT BINDINGS"
+.PP
+The initialization creates class bindings that give the
+following default behaviour:
+.IP [1]
+Clicking Button\-1 in a cell activates that cell. Clicking
+into an already active cell moves the insertion cursor to the
+character nearest the mouse.
+.IP [2]
+Moving the mouse while Button\-1 is pressed will stroke out a selection area.
+Exiting while Button\-1 is pressed causing scanning to occur on the table
+along with selection.
+.IP [3]
+Moving the mouse while Button\-2 is pressed causes scanning to
+occur without any selection.
+.IP [4]
+Home moves the table to have the origin in view.
+.IP [5]
+End moves the table to have the \fBend\fR cell in view.
+.IP [6]
+Control\-Home moves the table to the origin and activates that cell.
+.IP [7]
+Control\-End moves the table to the end and activates that cell.
+.IP [8]
+Shift\-Control\-Home extends the selection to the origin.
+.IP [9]
+Shift\-Control\-End extends the selection to the end.
+.IP [10]
+The left, right, up and down arrows move the active cell.
+.IP [11]
+Shift\-<arrow> extends the selection in that direction.
+.IP [12]
+Control\-leftarrow and Control\-rightarrow move the insertion
+cursor within the cell.
+.IP [13]
+Control\-slash selects all the cells.
+.IP [14]
+Control\-backslash clears selection from all the cells.
+.IP [15]
+Backspace deletes the character before the insertion cursor
+in the active cell.
+.IP [16]
+Delete deletes the character after the insertion cursor
+in the active cell.
+.IP [17]
+Escape rereads the value of the active cell from the specified data source,
+discarding any edits that have may been performed on the cell.
+.IP [18]
+Control\-a moves the insertion cursor to the beginning of the active cell.
+.IP [19]
+Control\-e moves the insertion cursor to the end of the active cell.
+.IP [20]
+Control\-minus and Control\-equals decrease and increase the
+width of the column with the active cell in it.
+.IP [21]
+Moving the mouse while Button\-3 (the right button on Windows) is pressed
+while you are over a border will cause interactive resizing of that row
+and/or column to occur, based on the value of \fB\-resizeborders\fR.
+.PP
+Some bindings may have slightly different behavior dependent on the
+\fB\-selectionmode\fR of the widget.
+.PP
+If the widget is disabled using the \fB\-state\fR option, then its
+view can still be adjusted and cells can still be selected,
+but no insertion cursor will be displayed and no cell modifications will
+take place.
+.PP
+The behavior of tables can be changed by defining new bindings for
+individual widgets or by redefining the class bindings. The default
+bindings are either compiled in or read from a file expected to
+correspond to: "[lindex $tcl_pkgPath 0]/Tktable<version>/tkTable.tcl".
+
+.SH "PERFORMANCE ISSUES"
+.PP
+The number of rows and columns or a table widget should not significantly
+affect the speed of redraw. Recalculation and redraw of table parameters
+and cells is restricted as much as possible.
+.PP
+The display cell with the insert cursor is redrawn each time the cursor
+blinks, which causes a steady stream of graphics traffic. Set the
+\fB\-insertofftime\fR option to 0 avoid this. The use of a \fB\-command\fR
+with the table without a cache can cause significant slow\-down, as the
+command is called once for each request of a cell value.
+
+
+.SH EXAMPLES
+.PP
+Set the topleft title area to be one spanning cell. This overestimates
+both row and column span by one, but the command does all the constraining
+for us.
