RST tables multirow cells rendering

[marian-code]

As I understand this is the lib that powers PyPI REDME rendering so I post this question here.

The problem

PyPI renders multirow cells in a way that it essentially ignores them which messes up the following rows. I have first encounterd this problem when trying to publish package to PyPI: https://pypi.org/project/ssh-utilities/ .

Minimal reproducible example

+---------------+---------------+
| title1        | title2        |
+===============+===============+
| col1          | col2          |
+---------------+---------------+
| mutirow       | cell1         |
|               +---------------+
|               | cell2         |
+---------------+---------------+
| singlerow     | cell3         |
+---------------+---------------+

Render this rst code with readme-renderer

python -m readme_renderer README.rst -o README.html

You will get this:

In the picture you can see the cell2 is incorrectly possitioned in the first column.

As far as I know RST is not supposed to render like this. So is this a know bug? Does any workaround exist? or is this on purpose?

Reviewing older issues, this one wasn't responded to.

This does appear to be a missing part of the functionality, as docutils supports this kind of table layout.

It's likely due to us stripping out the necessary directives to support this view during the clean() phase.
I'll add some tests and figure out the necessary directives to support this.
