Table Spacing on the web

Okay…got the &NBSP bit. Grazi! I’m working with inherited code here, so would appreciate any suggestions. Output/reporting to the web for this application consists of reiteratively appending multiple collections’ output to a RT field. Each collection has different fields in it, but the output report is formatted as a 5 column table (the “columns” of the table differ depending on the collection). At present all 5 columns of the table are the same width (the default). Is there a way to use RTfield.settab to make column 1 width X, column 2 width Y, etc)? Any other suggestions?
