I hope I'm understanding your question correctly; if so, you're better off avoiding manual column breaks which you'll then have to keep adjusting, and letting Word do the work for you.

Select the whole table and unset "allow row to break across pages" in the row properties. Then select everything except the last row of the table and set "keep with next" in the paragraph properties.

If you do that on all your tables you should get the layout you're after.
