Hi @pierrelouis , depending on your requirements, I have a component that you can attach to a table and it will copy a version of the table to clipboard.
It’s designed primarily for producing copies of tables that can be pasted into forum messages, and I added an option for “confluence compatible” too, which actually means “don’t include apostrophes around items which are necessary for it to work with the forum” ;-).
Of course whether this is useful to you depends on your needs.
There is of course nothing to prevent you from unlinking the component and modifying it if you need it to behave differently 
e.g. the following table has been copied/pasted directly using this component:
Universe_0_0 |
Universe_0_1 |
Universe_1_0 |
Universe_1_1 |

and this shows the copied data in “forum” format (top) or “confluence” format (bottom)
If you think this might be useful and have ideas of specific format that you would like copied to clipboard, feel free to make suggestions!
