There is no tagset for RTF in 9.1.3 that you can change. However, this PharmaSUG paper illustrates a technique for inserting RTF control strings into a file to delete the space above the table.

There is good news for SAS 9.2 -- by then, there will be a destination known as "measured RTF" and I believe that under that scenario, there will be a tagset to modify.

When he gets back he can verify this. The preliminary documentation, however, indicates that there will be a PARSKIP style element that you can change in a style template:
