Deleting a few cells from a table in Report Designer?

I have a report that has a table that is actually made of two tables. One table is columns Item and Amount, and Tax is it’s own separate table made to look adjoined. It looks like this in Designer

However when we actually make reports, it ends up looking like this -

Is there a way to make this all one table to keep it aligned, and just delete / hide the bottom 4 cells in the last column? Or some other fix? Not sure what to do, I’ve been fidgeting around with it in Designer for a while and can’t seem to get it.

The checking off of the visible property doesn’t seem to do anything on the cells.

Nevermind, I had to leave the page and come back and the cells were invisible.
