Maybe WebGrid(http://web2pyslices.com/main/slices/take_slice/39) can help you? I didn't use it but it says that it lets you build a table that supports paging, sorting, editing and totals easily.
Or you can put forms in a SQLTABLE column. How to add columns to SQLTABLE is being discussed in tread: Manipulate Rows Object and/or SQLTABLE http://groups.google.com/group/web2py/browse_thread/thread/87596d39a4e46c1b/01e764e9db39455b?lnk=gst&q=row+object#01e764e9db39455b
