I have two documents (A and B) with different margins. Document A has 1.5
inch margins and Document B has .5 margins. Document B also contains several
tables. I want to insert Document B at the end of Document A.

After combining these two documents, I must have a 1.5 inch margin
throughout. When doing this, however, my tables look as though they would
print off of the page (given that they originally had .5 inch margins).

Is there a way for me to bring Document B to Document A (keeping 1.5 margins
all of the way around) without it looking like the tables are going to print
off the page and without reformatting all of the tables? If Document B was a
figure or a pdf file, I would be able to scale the whole document down
without losing part of the document or without losing proportions. I do not
need the tables or any part of Document B to be editable once it is a part of
document A.
