7’ wide….you have to factor in pulling back chairs to get in or out. Minimum is 18” and that is tight. So, right off the bat you lose 3’ off the 7’. That sounds like a possibility, but every person will have to pull chairs under the table before they can leave. I will have to scout for photos, but it seems like you need a long table, pushed toward the wall and a bench seating on solid wall. Not perfect, but an option.

IMO no to the bench seating. Those on the bench will be held hostage to the WHOLE table of people having to get up to move the table out!
