1. can it possible to add buttons like ADD/DELETE at top of the Table below header?

2. It is possible to get sorting in table(like in ALV when click on field name Ascending and descending)?

3.How to use Drop down by index in table?

any suggestions?

any examples give me please...?

Thanks and Regards,
