I was referring to my original strategy, although I was doubtful whether such a method was possible. Unfortunately, the merged cells prevent formatting the current tables unless there is a workaround that I have not come across yet. If this way works, then that is all that matters really.

I tried your code yesterday and it worked great on the tables, but it seems to paste over 5-6 lines of text inbetween tables. I am still trying to figure out how your code works, but I'm wondering if this issue has something to do with the following part:
In one affected part I removed an extra line and then ran the code, which removed all remaining text (more than the 5-6 lines) between these 2 tables.
In another part, removing an indent/tab on a line under a table removed 2 more lines than before. I am still playing around with other causes, but hopefully you know more about this cause than I do.
