This will make implementing this part of the spec (which is already pretty
painful), even more painful... but yes, it may resolve the problem on the
table.

Of course going down this road and just declaring that spanning information is
part of the document structure, not of the layout does preclude ever having a
way to set spanning information via CSS (because then you would be back to
square 1).  That may be fine, all things considered.

Right.  That's the basic problem we're looking at.

How would this make the situation any better for a "generic table"?  The column
still depends on CSS properties, no?

Rather it makes stage 2 self-referential because styles of nodes start to
depend on the styles of their siblings....

I agree that that's a small price to pay if we act before such styling becomes
widespread.

I'd be curious to hear what Ian thinks of this proposal.
