FrameMaker -- removing heading rows in existing tables

[Jim Owens]

Recent online help work has exposed the fact that one of our table 
formats has a heading row that isn't needed. In print we never noticed, 
but in the Help, we're using a different background colour for heading 
rows, and we see a simple table with the first row in a different colour 
for no good reason.

Is there a convenient way to update our existing tables in FrameMaker so 
that the heading row is converted to a body row for this format?
