Hi, Michael,
It's a fact of life in Word that there must always be a paragraph mark at
the end of the document -- that's where Word stores formatting information
that applies to the whole document, and you can't get rid of it. If the last
thing before that final paragraph mark is a table, the paragraph mark must
be below the table, not next to it. If the table happens to extend to the
bottom of a page, then the paragraph mark will cause an apparently blank
page.
You can pull the paragraph mark back onto the page with the table by
slightly reducing font sizes or the Space Before/After settings of the
visible text, and you can try selecting just the final paragraph mark and
formatting it to a size of 1 pt.
Also, turn on the ¶ button and make sure there's only one paragraph mark at
the end of the document.
