Format cell in table by comparing to another value

I have a table that is setup as below. I need to change the cell background color based on a comparison of each cell to the requirement cell in that row. Column headers are going to be changing regularly as data snapshots are saved. KPI Requirement 09/13/17 22:30 09/13/17 22:45 09/13/17 23:00 09/13/17 23:15 KPI1 0.20 0.05 0.04 0.04 0.04 KPI2 0.20 0.10 0.09 0.10 0.10 KPI3 1.60 1.24 1.24 1.24 1.22
