+    \brief The QTableWidgetItem class provides an item for use with the
+    QTableWidget class.
+
+    \ingroup model-view
+
+    Table items are used to hold pieces of information for table widgets.
+    Items usually contain text, icons, or checkboxes
+
+    The QTableWidgetItem class is a convenience class that replaces the
+    \c QTableItem class in Qt 3. It provides an item for use with
+    the QTableWidget class.
+
+    Top-level items are constructed without a parent then inserted at the
+    position specified by a pair of row and column numbers:
+
+    \snippet doc/src/snippets/qtablewidget-using/mainwindow.cpp 3
+
+    Each item can have its own background brush which is set with
+    the setBackground() function. The current background brush can be
+    found with background().
+    The text label for each item can be rendered with its own font and brush.
+    These are specified with the setFont() and setForeground() functions,
+    and read with font() and foreground().
+
+    By default, items are enabled, editable, selectable, checkable, and can be
+    used both as the source of a drag and drop operation and as a drop target.
+    Each item's flags can be changed by calling setFlags() with the appropriate
+    value (see \l{Qt::ItemFlags}). Checkable items can be checked and unchecked
+    with the setCheckState() function. The corresponding checkState() function
+    indicates whether the item is currently checked.
+
+    \section1 Subclassing
+
+    When subclassing QTableWidgetItem to provide custom items, it is possible to
+    define new types for them so that they can be distinguished from standard
+    items. The constructors for subclasses that require this feature need to
+    call the base class constructor with a new type value equal to or greater
+    than \l UserType.

+    \class QTableWidget
+    \brief The QTableWidget class provides an item-based table view with a default model.
+
+    \ingroup model-view
+    \mainclass
+
+    Table widgets provide standard table display facilities for applications.
+    The items in a QTableWidget are provided by QTableWidgetItem.
+
+    If you want a table that uses your own data model you should
+    use QTableView rather than this class.
+
+    Table widgets can be constructed with the required numbers of rows and
+    columns:
+
+    \snippet doc/src/snippets/qtablewidget-using/mainwindow.cpp 0
+
+    Alternatively, tables can be constructed without a given size and resized
+    later:
+
+    \snippet doc/src/snippets/qtablewidget-resizing/mainwindow.cpp 0
+    \snippet doc/src/snippets/qtablewidget-resizing/mainwindow.cpp 1
+
+    Items are created ouside the table (with no parent widget) and inserted
+    into the table with setItem():
+
+    \snippet doc/src/snippets/qtablewidget-resizing/mainwindow.cpp 2
+
+    If you want to enable sorting in your table widget, do so after you
+    have populated it with items, otherwise sorting may interfere with
+    the insertion order (see setItem() for details).
+
+    Tables can be given both horizontal and vertical headers. The simplest way
+    to create the headers is to supply a list of strings to the
+    setHorizontalHeaderLabels() and setVerticalHeaderLabels() functions. These
+    will provide simple textual headers for the table's columns and rows.
+    More sophisticated headers can be created from existing table items
+    that are usually constructed outside the table. For example, we can
+    construct a table item with an icon and aligned text, and use it as the
+    header for a particular column:
+
+    \snippet doc/src/snippets/qtablewidget-using/mainwindow.cpp 2
+
+    The number of rows in the table can be found with rowCount(), and the
+    number of columns with columnCount(). The table can be cleared with the
+    clear() function.
