my cavalier king charles spaniel is refusing to potty train?

my cavalier is a yr old! no matter how consistent i am with house training, she refuses. if i take her outside, she cries and whines. so i tried paper training her (not such a good idea). i dont know what else to do
my cavalier is also bad. she has plenty of toys but instead she chews up the coffee table!!! she chewed all the legs on my new coffee table and the dining room table. i dont know what else to do. i do play with her, take her on walks, etc.
the other problem is she pukes everywhere. i limit how much food she eats but it doesnt help. she eats so quick she pukes. then if i put her in a kennel she will whine and cry and get serself so worked up she pukes. my vet had no advice for me except to spray the tables with bitter apple (didnt work)
