Bug #6949 for DBIx-XHTML_Table: set_group row-span and multiple column group feature

I have two feature requests for the set_group function: 1) Would it be possible to add a row-span feature where rather than replacing the duplicate value in the main column with &nbsp, the duplicate table td elements are simply deleted and the row-span td attribute is used to expand the first row across the duplicate rows? 2) Would it be possible to extend the set_group feature to other columns as well? In this case duplicate row elements would be replaced by the &nbsp or the cell could span multiple rows as in (1). This would produce a table similar to the one shown below. +---------+---------+---------+---------+ | HDR1 | HDR2 | HDR3 | HDR4 | +---------+---------+---------+---------+ | | COL2a | COL3a | COL4a | | COL1 | | | COL4b | | | COL2b | COL3b | COL4c | | | | COL3c | COL4d | | | | | COL4e | +---------+---------+---------+---------+ Thanks.
