Alternate infraction infotable backgrounds

[Kybyrian]

Hey guys, it's always been a little bit of a problem when issuing an infraction to a user to see that mono-colored background in the infractions table. My idea was to give each alternating infraction displayed a different background color (i.e. grey) to make for less mischecking and a need to highlight just to line an infraction and its checkbox up correctly.

(screenshot) This is the sort of stuff I'm talking about.

Now the raw HTML displays this as a table. And each separate infraction is held in a <tr>. My idea was to give each alternating <tr> a class, but the problem is I wouldn't know to go about doing this since it's not something you can just directly edit for each alternating infraction. Any help with this? Would be really appreciated.
