Well, maybe there's nothing similar in HTML as there's actually nothing
similar.
Tables are 2D structures within a 1D tag stream.
I'd say this is enough to make them unique.
I would not deprecate <col>.
How would you define "column properties" in a table?
Cell by cell?

Not at all!
I'm just suggesting to make CSS more powerful and useful.

CSS can be extended this way: columns CAN BE parents of cells (just like
rows are), despite their position in the syntax tag flow.
I think that once you accept this concept, everything can fit.

That's interesting indeed. But IMHO it's also duplicating the <col>
concept that's already in place.

I appreciate a lot the job of the CSS GW and am far from criticizing it.
