Yeah, I don't think that would work. I don't believe the column tags are
evaluated for each item in the list iterator, which is how the JSTL tag
would deal with it. Basically, if that condition was true the first time
thru, then the table would be evaluated for all rows. If that condition
wasn't true the first time, then the table would not be evaluated for ANY
rows. At least, I *think* this is how that would work.
I think, basically, you're out of luck trying to use displaytag to filter
out specific rows. I think you need to filter the list before sending it
to the table tag.
