When you are in a table match, you can actually win the match by putting them through the announce table. You have to get your opponent laying on the announce table and then you climb on to the turnbuckle. Then you simply jump off by pressing X. If you managed to put them through it, you win the match via Knockout.

However, this is quite hard to do. Your opponent pretends to keep rolling off the table as you jump, so you really have to knock him or her out for this to work!
