CellTable, DataGrid and in general all widgets that implements HasKeyboardPagingPolicy, have a KeyboardPagingPolicy field that can be set to INCREASE_RANGE in order to append the next page instead switching to it. Showcase shows this functionality with CellList, using a ShowMorePagerPanel (that extends AbstractPager) that uses an inner ScrollPanel to update the current range once the scrollbar reaches the end. But for the DataGrid should be the same: define the pager, add it to the DataGrid and set the KeyboardPagingPolicy.
