Word requires a paragraph after a table. There's no way around this. 

You can work around this issue as follows: 
- before the table, insert a [section break (next page)][1]
- then, reduce the bottom margin of your last page, by going to `Layout -> Margins -> Custom Margins`, (as [described here][2]) making sure that in the `Apply to` box is selected `This section`.
 
Like this, the paragraph mark will stay below the table, but still on your last page.
