it seems you are going to need to wire in the maruku dialect they have, so on the upside a lot of the code is already there to support this.
@codinghorror we need to pick a poison here:
- We do no want markdown table support on by default
- We are ok with markdown table support on by default
- Markdown table support must come from a plugin
- Markdown table support can be in core but must be default off
Regardless, this is not work we are embarking on in the next few months, so it would have to be contributed via the community.
