You can find anything on the internet!

I noticed this workbench in a YouTube video. The bench was used for various printers. Note the receptacles.
(No, that’s not me in the pic).

Does the code care that this is a “workbench,” rather than a “counter top?”

I've seen pop-ups that are listed, and $$$; and a few that have issues. A few were plug & cord connected with a 16 Ga. cord, no listings.

Pop-ups are becoming very popular in commercial jobs also. Some are very interesting designs, and all I have come upon are listed.
