Gluing top on table-wood movement?

I really cannot picture a table where grain direction is matched to the
top. The apron has grain running horizontal all the way around, which
means it will be cross grain on two sides. Do you have a picture?

Plywood can probably be safely considered movement free from the point
of the design.

Ah, indeed it is. This is quite unusual table design; normally all apron
grain runs horizontal as the "normal" apron is narrower then you have
used. Hence, when you say you have a "table" and ask about attaching the
top, people assume the normal cross grain situation. I can't see any
specific reason why attaching the top down all the way around won't work
in your case. Perhaps someone else can.

The grain on the backruns the same as the top, as do the sides. I intended
on using pocket screw in the legs to hold the top on, but it turned out not
to be possible.
