When trying to color the entire row containing numbers, it only colors in the values and not the entire row. How could I get it to highlight the entire row?

With the information you provided so far, I can unfortunately not reproduce the issue you describe. Could you please prepare a complete and compilable small example document that allows others to reproduce the output you get? — leandriis, Feb 28 '20 at 13:38
Why do you declare 5 columns? Your table seems to only need 4 columns? Please also comment on the use of ~ throughout your table. — leandriis, Feb 28 '20 at 13:49
5 columns was not meant to be used however it made the table look how I wanted it to and I neglected to correct it. The use of ~ was to make spacing between columns the size I wanted (Did not know another way). — MarkDingerz, Feb 28 '20 at 14:03
Thans for the update and the comments. revtex4-1 and colortbl doesn't fill cells seems to be related to your issue as well. — leandriis, Feb 28 '20 at 14:05

Seems ok - probably something in your preamble
