Of all your friends who sit at that table, discern which one is the most approachable and understanding, and talk to them about why you don't like sitting with that person. If that fails, then stop sitting at that table completely, and if one of your friends asks you why, explain to them why you don't like sitting there. Hopefully, if they're really your friends, they'll try to mend the situation.
Good luck!
