Your question is a bit confusing. Let me see if I understand correctly.
You want to create a spreadsheet like table that has 5 columns and unlimited rows and have it appear in somewhere on the screen of your filemaker application.
An example might be like an invoice where the bulk of the main screen contains header information like customer name, address, phone, terms, PO number, etc. Then within this screen there is a scrolling table of invoice lines that contain stock number, description, unit price, extended price etc.
If this is the kind of thing that you are wishing to do then you should read up on Portals. A portal is a window into data that is contained in another database table but is related to the record that you are viewing.
If you need more help let me know.
