I guess so. STUB seems to be used more in listings, though, for a row
label value which is implicitly repeated without being printed (what we
used to use ditto marks for :-) RED/BLUE/GREEN I would have called
"row header" or "row labels" by analogy with "column headers" but that
may just be my computing side showing thru. I don't think it's very
important so long as we all know what we mean.
What you say above about them is absolutely true and usually neglected
by table designers. Let's not make the same mistake in HTML3.
