how to use it?

[topic title moderated]

I installed the plugin grid columns by justin tadlock and i am having the hardest time trying to figure out how to use it. I do not understand the short code. I want to create a grid within one of my pages that has 2 columns. Can someone give me an example of how I would do that?

For example i am trying to alphabatize some restaurants and I want to list restaurants on the left and addresses on the right.
