* TBaseDataList class
*
* TBaseDataList is the base class for data listing controls, including
* {@link TDataList} and {@link TDataGrid}.
*
* The key field in the data source is specified by {@link setKeyField KeyField},
* while {@link getKeyValues KeyValues} stores the key values of each record in
* a data listing control. You may use the list item index to obtain the corresponding
* database key value.
*
* TBaseDataList also implements a few properties used for presentation based
* on tabular layout. The {@link setCaption Caption}, whose alignment is
* specified via {@link setCaptionAlign CaptionAlign}, is rendered as the table caption.
* The table cellpadding and cellspacing are specified by
* {@link setCellPadding CellPadding} and {@link setCellSpacing CellSpacing}
* properties, respectively. The {@link setGridLines GridLines} specifies how
* the table should display its borders, and the horizontal alignment of the table
* content can be specified via {@link setHorizontalAlign HorizontalAlign}.
