Tables in Multimarkdown are not rendered properly

[EmacsPrimer]

Summary: Tables in Multimarkdown are not rendered properly

Here is the page that demonstrates the bug: http://emacs-primer.branchable.com/bugs/Text_Editing_Essentials/

Note that the second table is rendered properly while the first and
last tables are clobbered. I expect the first and last table to be
rendered without any header rows.

This bug is forwarded from http://www.branchable.com/bugs/Tables_in_Multimarkdown_are_not_rendered_properly/

Here is the markdown content.

This is what is reported when I commit the above page.

Going by this link: http://fletcher.github.io/MultiMarkdown-5/tables.html, that's not a proper table. Tables have worked fine for me with Text::MultiMarkdown. The first MD row must contain table headers, the second MD row contains alignment instructions. The table data starts in row 3. A correct table would be:

# Keys

| Notation | How to read it | Where on the keyboard |
|-----------|------------------|----------------|
| C         | CONTROL key    | CTRL, CTL             |
| M        | META key       | EDIT or ALT           |

And it renders as:

Keys

Notation	How to read it	Where on the keyboard
C	CONTROL key	CTRL, CTL
M	META key	EDIT or ALT

I hope you can see the source of this post. And the rest of your tables:
