What an impressive thread!
@Yassine I want to thank you for your ideas for the plugin! I just want to clarify the scenario with you and @antares
Are we talking about the tabulation in the cell of the table in the .docx file or about the cell in the .xlsx file? If it’s the first scenario, recently we checked it here: Brochure suggestions 8/22: no tabs in tables - #10 by Alexandre
Unfortunately, the only possible way for the first scenario is copying and pasting. But we are working already on implementing custom hotkeys feature. It should resolve the situation.
If we are talking about the second scenario (tabulation in the cell of the .xlsx file), please clarify it.
