Misbehaving at the dinner table

So Greta has been a little pistol during dinner. She thinks it's okay to put your feet on the table. 

So in a result to fix this. I pulled her chair away from the table. This then results of her getting mad. And then her rocking her chair. Almost to tipping her over. When I feel there's no resolve, I tell her she needs to go sit in the hallway. 

 This has backfired. She actually enjoys to go sit in the hallway. Tonight she actually asks to go sit there. Ugh!! 

Now what??
