The shortest answer, since you found an example, would be: look at the page you found and see how it was done.
I suspect that it's not the <tr> row element that has a background, but instead each <td> cell has its own background.

Whichever function you create, of course. 
All you'd need to do is to keep track of what color the previous row began with and pick the alternate color for the current row. For the second/third/Nth cells within that row, you do the same logic (using the previous cell instead of row) to figure out which color to use.
