Try highlighting all of the table starting from A2, and use the "Use a formula to determine which cells to format" option. Then in the formula bar use this formula:
=$B2="reviewed"
(untested but should work)
Edit: I should note that your "reveiwed" appears to be spelled wrong. Assuming that's a typo here, there shouldn't be any problem, but if it's spelled that way on your worksheet you will need to change the spelling, or change the formula.
