In general any type of training that involves a ball will be good for you.
Good table tennis players usually are quick learners when it comes to tennis.
It's true that you use the wrist more in table tennis, but the hand eye coordination practice plus the training in judging angles, speed and spin can be directly used in tennis or any other ball game. At the same time you will benifit from the swift reactions that you gain from playing table tennis.
Anything that improves your motor skills will of course be good for you on the tennis court.
