Expanding rows crowd form

Please help me with this problem:

In Adobe livecycle designer es I have an xdp file with a table with add/remove row buttons that work.  However when I add rows to the run-time pdf, the table expands into the footer or the next subform, crowding out or overwriting other things on the form.

How do I automatically set the table or row (this row is known as a "detail") so that when I add a new row, the area alotted for the table automatically expands and it doesn't crowd/overwrite other sectiosn or elements on the form?

Thanks in advance.
