Table flashing or color change

I have 3 column table, I will need one of t开发者_StackOverflow中文版he columns to give me color change notification or flashing, how to do this?

There's a (rather annoying) simple JavaScript code snippet here that does this:

You can make it less annoying by reducing the number of colors and increasing the delays :)

Note that you'll have to modify it from using the entire document to using just the element(s) that you want to change. I'm guessing a bunch of td elements?
