You would have a much better chance of seeing what the issue is if you turned on Word's formatting display, which you do by clicking on the ¶ symbol on the Ribbon's Home tab.

Table end-of-cell and end-of-row markers are indicated by the '¤'symbol. You can't delete those. Any →, ↵ and ¶ symbols represent tabs, line breaks, and paragraph breaks, respectively. You may have some of these that you don't need/want and are causing the problem.

Beyond that, it's a matter of table formatting and/or paragraph formatting but, without access to the affected table, we can't tell.
