Hi
It's too late for me, I've never managed to stop my two counter surfing in the kitchen or getting on the table (although to be fair we don't eat at the table and the table now has their beds on it
). However I read somewhere that you should buy some cheap table mats, sticky paws (a double sided tape that won't harm her) and place these where you don't want her to go. It makes it less of a pleasant experience apparently and she'll decide it's not a good place to be when her paws stick to the mats. Normal remedies such as kitchen foil certainly didn't phase my two.
However, this is a Bengal and quite often nothing works! They are, as you are discovering, very persistent and very determined.
We always used to shut our two out of the room when we were eating but these days they're not so interested. As kittens what us strange humans do is ever so interesting and she's learning about you, so she will be keen to be nosy about every action you take to see if it might be fun for her to join in!
Good luck!
