      public abstract class AbstractExtendedDataTable
      extends UIDataTableBase
      implements MetaComponentResolver, MetaComponentEncoder, EventsRowProps, RowsProps, StyleProps, StyleClassProps, SequenceProps, IterationProps, AjaxActivatorProps

  The <rich:extendedDataTable> component builds on the functionality of the <rich:dataTable> component, adding features such as scrolling for the table body (both horizontal and vertical), Ajax loading for vertical scrolling, frozen columns, row selection, and rearranging of columns. It also supports all the basic table features such as sorting, filtering, and paging using the <rich:dataScroller> component.
