The easiest solution would be to adjust the paragraph spacing. If this is a document that will be frequently edited, i do not recommend that as a solution--you will have to constantly tweak the spacing.

How much white space do you have at the bottom of the page? If it's just 3-4 extra lines, it's not a big deal. If you have a large table, resulting in a LOT of white space, it's possible you might be better off allowing the table to break across two pages.

Would it be possible for you to post the two pages in question? If we have a better idea of the problem, we'll be in a better position to offer a solution.
