How to use conditional formatting in excel based off of another table

Question

I am trying to highlight cells in column G based off of whether or not the cell contains any of the text strings I have entered into another table, specifically the Pgroup table in Column U. I would like this to become a flexible conditional format based on text strings that can be added to or subtracted from the secondary table based on a project basis. I have tried a couple different ways but to no avail. Any help would be appreciated. I know I can enter another condition for every text string but thought this would be a better alternative since my text strings can change regularly. I am trying to do this with different columns and different reference tables as well but if I can find a way to make it work with one I think it will work with all. Not all will be absolute matches, I'd also like to be able to search for text strings inside of a cell that contains more than just the text string I'm looking for. My File

Answer 1

Conditional formatting --> New Rule --> Formula -->=SUM(COUNTIF($A2,$P$2:$P$7))
Where A2 is the start of a column to format and P2:P7 is where your values are located.
To format the whole row, set "Applies to" to $A$2:$endOfYourTable
