Just go in and say his current setup is NOT fitting your needs and start moving his furniture!!
Ok, maybe not but it sounded like a nice idea for you. Yes, definitely ask about moving the table...I mean, is there anything on it? My ex-T had a glass table to the side of us against the wall with kleenex and his stupid Freud mug on it (that almost got a bashing from me, or perhaps a pitching against the wall?). But I hardly noticed the table where it was placed, and it also had utility.
Anyway, I bet you are not the only one who feels that way about that table. I would say you should def. be able to sit closer and be sure to ask for what you need and explain why. I think my pdoc, if he weren't to move his chair away from his desk and over for our sessions, would be about that far away (10 feet or even more) and it would drive me nuts.
Good luck banishing the table to elsewhere and getting what you need!
