Ah, but you must assume the table is still there. But you cannot say with certainty that the table is there unless you open the door. And even then, all that you know is that it was there before you shut the door and after you opened it again. You must ASSUME that it is still there when you can't see it. That's what science does. Make educated guesses as to what is most likely. It is most likely that the table stayed there, but it could have teleported or flew to the moon and back again right before you opened the door.
