you have no idea how long I’ve wondered how to do this:

you'd think it would be easy, right?  Format Excel sheets to alternate row color so that its easier to read, especially when you print it out.  And it is easy, once you know how:

Excel: Automatically alternate row colors (dynamically)

Oh, and if you are wondering how long I've been wondering how to do this - at least 2 years, and I just now took the time to do the 1 minute google search to find the answer.  Well, maybe this will save some time for you.
