📝 Provide a description of the new feature

Follow-up for the #3287: This issue gathers content compatibility issues from the CKEditor 5's default conversion of various table properties.

The following applications should be covered:

• CKEditor 4
• Word
• Excel
• Google Docs

Most likely, work on each of those platforms will happen separately, but there's some overlap, so we need to make sure to make correct decisions when adding code to either ckeditor5-paste-from-office (normalizators) or ckeditor5-tables (converters).

If you'd like to see better support for pasting tables from one of the above mentioned apps add 👍 to this ticket and explain in a comment which apps are crucial to you.
