Good work.
Suggestion: I think your full-cell color is too much and black on red is never good. Here's a trick:
Modify the style and set the left border to 20 px and add some color there instead. You get a nice indicator with an easy-to-read text beside it. There is no need to "scream" color! Be cool, man! Be cool!
You need to do this for each different style that you use.
