@petyosi , is this helpful? this allows the collaboration plugin to work with tables etc.
unfortunately without this tables dont seem to work.

happy to contribute example code for the collaboration plugins.

I'm afraid that I don't understand the implementation of this PR. In addition, the code is not formatted and has some basic issues.

• A lodash dependency is introduced, for a single equal.
• yjs packages are imported but not added to package json. The imported Provider is unused.
• The extensionsRef is unnecessary. The extensions can be constructed in useMemo. I'm also not sure why the code there exists.
