Interactive Sort in Matrix

I have a Matrix in a report - created like below. Each row has a different dataset and I need to make each Column to be sortable so they can click on the column header say "Summary of Accounts" and sort them and do that for each column header. So far I havent seen anything that looks promising that can do this. Is there away this can be done?

6 Columns and 14 Rows

--headers

Summary of Accounts No debts origBal AccrInter PaidDate CurrBal

Activity count() Sum() Sum() First() Sum()

phase count() Sum() Sum() First() Sum()

The combination of Interactive Sort and Matrix are not good! I managed to get it working but only for row groups.|||I know they are not how about how did you do the row groups? If they can sort by row then fine that is good enough for me then!
