Heads up! This blog post hasn't been updated in over 2 years. CodePen is an ever changing place, so if this post references features, you're probably better off checking the docs. Get in touch with support if you have further questions.

We support Markdown pretty much everywhere on CodePen. We just tweaked it a little bit to now allow tables everywhere. You could always do HTML tables, but Markdown tables are a little quicker to write out. They look like this:

|     | this  | little  | piggy |
|-----|-------|---------|------:|
| one | alpha | hello   | 0.001 |
| two | beta  | goodbye | 0.002 |

The right row is right-aligned. It's pretty easy to memorize, but there is a great generator tool if you forget.

Used a Pen description, you'll get simple styles like this:

Feel free to use them in comments or on your blog as well.
