I just remembered something mine did. I had a cookie in my sewing room in a baggie and the next morning it was gone! I couldn't believe cats like cookies and I was worried she'd get sick but she didn't seem to have any ill effects from it. Cats do the darnest things. I wish you luck in keeping her off your table. Does she have a perch or something like that, that she can climb on? Maybe that's what you need to do. She sounds bored to me.
