Raw Handling: unexpected results when pasting table with list from Google Docs

[danielbachhuber]

Description

I tried pasting a table from Google Docs and received unexpected results.

Google Docs

Gutenberg

Notably:

1. My merged bottom cell doesn't span full width. I assume this is blocked by Table block: Merge/Unmerge cells #15821
2. My unordered list in the bottom cell lost its formatting. To avoid going down the Table Block: Should we use InnerBlocks? #18768 rabbit hole, I'd be fine with it transforming to:

Related #32400

Step-by-step reproduction instructions

1. Copy table from https://docs.google.com/document/d/17fBRHVwvr9OUzvVR0H1S5-YJ8KKUam1kgnh4X9vtWgU/edit?usp=sharing
2. Paste table into Gutenberg
3. Observe results

To resolve this issue, I'd like to propose two separate PRs:

1. Support the colspan attribute on the underlying HTML (from Table block: Merge/Unmerge cells #15821 (comment)) with a test case for pasting from Google Docs.
2. Transform unordered and ordered lists within tables to simple list representations on paste.

I am going to start this. You can assign this issue to me if you like (I can't do that myself).

Thanks for adding colspan support!

I would suggest adding further rowspan support, what do you think? I would be happy to help with the work.

Sounds good to me, @t-hamano. It should be easy to use this PR as a template for rowpan too.
