So the issue comes when using tables.
Make a table cell end at the bottom of the page, and you'll likely have a new blank page appear at the end.
The reason is because word needs a 'new paragraph' marker (the backwards p symbol) after the table. This delineates where the table ends - it's part of the formatting. You can't delete it.
Ways to get around it:
- Don't make you're table go to the end of the page.
- Reduce the font size of the new paragraph marker to 1 (you need to enable show formatting marks). You can probably fit this at the bottom of the page without losing much space.
