Table of Contents text alignment

Hi!

I added a Table of Contents block to one of my posts and I would like to show it centered. I was wondering if there is a way to have the text left aligned when the content is centered? Now both the content and the text is centered, but I think it would look better if I had the centered box with text aligned to the left side of it.
