I have 2 boys who are obsessed with human food also. I don't know why either because I do what you do, no feeding from the table, all food goes in their bowl in the kitchen AFTER we are all done eating and cleaning up, etc... What I started to do was tell them to go to the kitchen when we are eating (table in dining room) so they go to their bed in the kitchen and watch us from there. After we are done eating, if they were good I save a small small portion for them and give it to them on a plate on the kitchen floor. If they do not behave they get nothing. One of my boys used to jump or climb on your lap while you were sitting eating at the table. I make sure all chairs are pushed in all the way so they cannot use the chairs to get on the table. I don't know if that will help you but try gating her somewhere when you are eating and repeating to her where she is, like 'kitchen' thats what I did. So now I don't have to gate mine, they automatically go there and stay there until we are done eating. Its a much more pleasant meal time for us without them begging at our feet the whole time.
