Two tables in main window of smart form

I have 2 different internal tables that need to displayed in main window.

upper part of the main window should be displaying first table and lower half should disply 2nd table.

this page should be repeated depending upon number of rows.

When I include bothe tables in main window, its displaying first table first and then 2nd table.

I want both tables to be displayed simultaneously...

Can anyone help me?

Thanks & Regards,

Kalyan Venigalla.
