Possibly; however, I don't see how treating it as display: none is
consistent with 'This allows dynamic effects to remove table rows or
columns without forcing a re-layout of the table in order to account for
the potential change in column constraints.', since if the row is being
display: noned, then the table must be reflowed. It's a pity Opera 4
doesn't support it, so then we could see what it's meant to mean from
the person who wrote it (?) :-).
