The term for this is “weaponized incompetence” or “strategic incompetence” and it’s definitely a way of avoiding doing a task. Of course he knows how to clear the table, as others have pointed out even a child could do it. It could be sub-conscious, but that’s almost just as bad, because he’s probably never HAD to think of how to clear up, the house just gets tidy and he doesn’t think of how that happens, and doesn’t appreciate the work it takes.

My husband does this too, so sometimes I like to pretend not to know how to so something basic right back at him to make my point and make him laugh. “Dinner? What’s that? I’ve never heard of it. You’ll have to make it”. “What are these things? Cutlery! I’ve never seen them before, wow. Could you cut my food up for me? I just don’t know how”. Yes it’s petty, but so it pretending (or not bothering) to clear the table properly because your wife will do it for you.
My DH used computers when he was at work, programming river flow and doing all sorts of complicated techy things that no mere mortal could manage. However now he has retired he refuses to use a mobile phone or a computer, pretends to have trouble using the address book and menus on the landline and all sorts of irritating day to day trivia.
His banking still has to be done in the branch, including paying in and transfers, so today I've bought him a mobile phone and he'll join the 21st century tomorrow.
