How to create a data grid?

I have data that I need to display in my blog, and I think that a grid is going to be the easiest way to make the data easy to comprehend by my readers. Grids are nice, clean, and visually appealing. However, I have no idea how to make one in WordPress. Is there a built in grid feature in WP (if there is, I can’t find it)? If not, how would I go about doing this? Can I just make an Excel spreadsheet and then cut and paste it into my blog? Please help.
