Inserting row at certain position in tableview

I want to insert rows after rendering tableview into a certain category or in-between rows. Anyone done this or looked into it?

until reRender comes back I think your only way is to empty your table and redraw the whole thing. Quite efficient with tables with less than 500 records in my opinion but not ideal of course.
