If 1998 (publication of CSS2) is last minute, I agree with you, it is
not intuitive in some cases. But I'm not sure we can change it, given
the amount of currently published content for which it works.

Maybe Tables 3 or Tables 4 may include a "flexible" table algorithm

That's the point of having a normative algorithm for implementers. If

came out with almost full CSS2 support). You should ask the designers
of <table>-based websites.
