Section 17.6 of CSS2 clearly defines the formatting model in the two
border models, and neither of these involve the use of padding on any
table elements other than cells.  The spec defines a formatting model
for tables that conflicts with, and therefore overrides, other
formatting models described in the spec.  It doesn't need to state that
the overridden parts of the other formatting models do not apply.

You are correct that it *could* make such a statement, and it might be
clearer to do so.  However, the absence of such a statement does not
imply anything.  (I guess it could also be stated explicitly that the
sections on table formatting are authoritative when it comes to tables,
although it's usually clear which sections of the spec override
others.  It might also be better to state the exceptions to the rules
where they are originally defined.)

The original proposed border model in early drafts of CSS2 did involve
a full(er) box model on all elements, but I imagine it was scrapped
because it was too complicated.  I guess it could reappear, but it
would have to do so as a third border model.
