Current behavior
RowGroupFooter (pTemplate="rowgroupfooter") has no own class name for styling

Expected behavior
It would be great if you add an additional class name (e.g. "ui-rowgroup-footer") in the tr-tag for the row group footer.

What is the motivation / use case for changing the behavior?
More flexible design posibilities
