Markdown blocks wont render tables

[HenryMBaldwin]

Content Kit markdown blocks wont render tables. On top of this, content kit is so limited that there's no way to actually make a consistently clean table using content kit in an integration. This on its own is really annoying, however this seems like a choice, whereas the markdown element not rendering tables seems like a bug.

Definitely on our list to improve content kit blocks in general - thanks for the feedback @HenryMBaldwin
