In Table view, right-clicking the table in the central area and choosing Copy or Copy Table doesn't do anything. Nothing is copied.
I found a "workaround" with the Query View here: Solved: Re: I can't copy table on "Data" Page in power BI - Microsoft Fabric Community
Sadly this is not a real workaround, since eg. dates are stored in the most horrific way afterwards. Example (stored as text): "Tue Sep 04 2018 00:00:00 GMT+0200 (Central European Summer Time)"
