Comparative Statement

Dear Guys

I am developing a comparative statements having vendor names as table colums and details below the vendor name.

Now a problem is that each vendor can have different line items. For egample if I write 10 line items for first vendor , how can I go back at top for writing the detials of second vendor from top to down.

Example

Vendor1 Vendor2 Vendor3

XY

XZ

22

Now in above example If had printed the data till 22 for first vendor how can i start writing from top line once again for vendor 2 becuase I think ABAP dont support to go back on first line.
