Horizontal table scrolling

Hi all

I have to normal tables underneath eachother.

I have set fixedPosition on column and scrollablecolcount on table.

When I use horizontal scroll bar, I want the second table to also scroll to the same position...

I set firstVisibleScrollableCol to sync the tables.

Problem is the onscroll event of the table only fires when the table scrolles vertically.

Which event could I use to to sync the 2 tables horizontal scollbars when one of the to horizontal scrollbars are used?

thanks
