Custom anchor in markdown Text orTable


I would like to create a custom anchor in a table cell of a markdown document in gitlab.
The idea is then to link to this anchor from another document like one can do it with the rendered anchors of the markdown headers.

I’ve searched the documentation but could not find something about the issue.
Any hints would be great.

What I’ve already tried are the following combinations:

{: #foobar}
[](){: name="foobar"}
<a id="foobar"></a>

All do not work when rendered in the browser.
