remark-grid-table: incomplete multirow after correct row is not properly eaten

[artragis]

Sorry for the really long title, but this cas appears in only some weird circumstances :

• if you are creating a grid table
• when you start a multi-row line but do not properly write it

then zmarkdown fails with "improperly eaten" error

In real life, this happen when people tries to render tables with sub total.

Here is the minimal code to reproduce :

+---+---+---+
| A | B | C |
+===+===+===+
| D | E |F  |
+---+---+---+
| G | H | I |
+ K :   +---+

it renders the three first lines but fails to render the last one and whatever follows the table.

What is expected is that the two last rows (G H I and K) are rendered as plain text

[StaloneLab]

Pandoc expects it not rendered at all, because no empty space between last row and extra row.

I don't really know what is the expected behaviour, but anyway it's a bug.

[artragis]

In fact not rendered at all or only two first rows rendered is ok for me. The advantage of the second is that we know where the problem is more easily

I guess it's the same bug, so I'm commenting here. With the following Markdown

+------------+-------+

|            | Prix  |

+============+=======+

| foo        |  50   |

+------------+-------+

| bar        |  50   |

+============+=======+

| zz         | aff   |

+------------+-------+

I have the following error and stack trace:

I saw the error on Sentry, and this is expected: a table must not have two headers.
The error should disappear if one of the lines with = uses - instead.
