+    \class TQDataTable qdatatable.h
+    \brief The TQDataTable class provides a flexible SQL table widget that supports browsing and editing.
+
+    \ingroup database
+    \mainclass
+    \module sql
+
+    TQDataTable supports various functions for presenting and editing
+    SQL data from a \l TQSqlCursor in a table.
+
+    If you want a to present your data in a form use TQDataBrowser, or
+    for read-only forms, TQDataView.
+
+    When displaying data, TQDataTable only retrieves data for visible
+    rows. If the driver supports the 'query size' property the
+    TQDataTable will have the correct number of rows and the vertical
+    scrollbar will accurately reflect the number of rows displayed in
+    proportion to the number of rows in the dataset. If the driver
+    does not support the 'query size' property, rows are dynamically
+    fetched from the database on an as-needed basis with the scrollbar
+    becoming more accurate as the user scrolls down through the
+    records. This allows extremely large queries to be displayed as
+    tquickly as possible, with minimum memory usage.
+
+    TQDataTable inherits TQTable's API and extends it with functions to
+    sort and filter the data and sort columns. See setSqlCursor(),
+    setFilter(), setSort(), setSorting(), sortColumn() and refresh().
+
+    When displaying editable cursors, cell editing will be enabled.
+    (For more information on editable cursors, see \l TQSqlCursor).
+    TQDataTable can be used to modify existing data and to add new
+    records. When a user makes changes to a field in the table, the
+    cursor's edit buffer is used. The table will not send changes in
+    the edit buffer to the database until the user moves to a
+    different record in the grid or presses Enter. Cell editing is
+    initiated by pressing F2 (or right clicking and then clicking the
+    appropriate popup menu item) and canceled by pressing Esc. If
+    there is a problem updating or adding data, errors are handled
+    automatically (see handleError() to change this behavior). Note
+    that if autoEdit() is FALSE navigating to another record will
+    cancel the insert or update.
+
+    The user can be asked to confirm all edits with setConfirmEdits().
+    For more precise control use setConfirmInsert(),
+    setConfirmUpdate(), setConfirmDelete() and setConfirmCancels().
+    Use setAutoEdit() to control the behaviour of the table when the
+    user edits a record and then navigates. (Note that setAutoDelete()
+    is unrelated; it is used to set whether the TQSqlCursor is deleted
+    when the table is deleted.)
+
+    Since the data table can perform edits, it must be able to
+    uniquely identify every record so that edits are correctly
+    applied. Because of this the underlying cursor must have a valid
+    primary index to ensure that a unique record is inserted, updated
+    or deleted within the database otherwise the database may be
+    changed to an inconsistent state.
+
+    TQDataTable creates editors using the default \l TQSqlEditorFactory.
+    Different editor factories can be used by calling
+    installEditorFactory(). A property map is used to map between the
+    cell's value and the editor. You can use your own property map
+    with installPropertyMap().
+
+    The contents of a cell is available as a TQString with text() or as
+    a TQVariant with value(). The current record is returned by
+    currentRecord(). Use the find() function to search for a string in
+    the table.
+
+    Editing actions can be applied programatically. For example, the
+    insertCurrent() function reads the fields from the current record
+    into the cursor and performs the insert. The updateCurrent() and
+    deleteCurrent() functions perform similarly to update and delete
+    the current record respectively.
+
+    Columns in the table can be created automatically based on the
+    cursor (see setSqlCursor()). Columns can be manipulated manually
+    using addColumn(), removeColumn() and setColumn().
+
+    The table automatically copies many of the properties of the
+    cursor to format the display of data within cells (alignment,
+    visibility, etc.). The cursor can be changed with setSqlCursor().
+    The filter (see setFilter()) and sort defined within the table are
+    used instead of the filter and sort set on the cursor. For sorting
+    options see setSort(), sortColumn(), sortAscending() and
+    sortDescending(). Note that sorting operations will not behave as
+    expected if you are using a TQSqlSelectCursor because it uses
+    user-defined SQL queries to obtain data.
+
+    The text used to represent NULL, TRUE and FALSE values can be
+    changed with setNullText(), setTrueText() and setFalseText()
+    respectively. You can change the appearance of cells by
+    reimplementing paintField().
+
+    Whenever a new row is selected in the table the currentChanged()
+    signal is emitted. The primeInsert() signal is emitted when an
+    insert is initiated. The primeUpdate() and primeDelete() signals
+    are emitted when update and deletion are initiated respectively.
+    Just before the database is updated a signal is emitted;
+    beforeInsert(), beforeUpdate() or beforeDelete() as appropriate.
