Rich UI DataGrid and DataGridTooltip
A Rich UI dataGrid widget defines an array of row values
in a table. This topic gives general information about the widget
and then provides reference detail.
Rich UI GridLayout
A Rich UI grid layout has variably spaced rows and columns
that embed child widgets. Each child widget has a layoutData property,
and you specify the location of the widget by assigning a value to
that property. Your layoutData settings
also can align the widget horizontally and vertically within the position
and can cause the widget to span multiple rows and columns.
