Feature Request: Table Option

[matt-shirey]

I like the format of the @color element and think it would be nice to have a table one.

I'm currently using nucleus to generate a styleguide of the elements that "editors" are allowed to use when creating pages and a table would be nice. Example: https://getuikit.com/docs/base#text-level-semantics .

I would like to be able to use Markdown to show the element and then a description.
