Table control means it contains as table and it will scroll in vertical and horizontal.
In module pool by using screen we can create new table control.
But BDC table control means here we can populate the data into the table control.
i.e.if you take VA01 for sales order creation in the belwo of VA01 screen there is table control for the filling of material details so here we will write the code to populate the data into the table control screen.
Thanks and regards,
