Drawing Table Repeat Region(BOM) releations

What do mean by 'format the repeat region'?

You cannot add or remove columns from the table based on certain parameters. The table is a fixed design. You can hide rows of data for certain part numbers based on its value.

Repeat regions are driven by the assembly and their components (mostly parameters). Assemblies and parts don't track have anything that refers to a drawing within them.  Unless your drawing number is a parameter from within your parts or assembly, I don't think you would be able to use that.
