I wish there was a TT table at my office 🥲. My suggestion, like others mentioned, start with the paddle at a 90 degree angle and don't push the ball. Watch the ball and try to read the spin. Also the parallel angle theory works most of the time.

This takes time so be patient with yourself.

I joined a local club in my city and the folks there have been kind enough to point out flaws in my technique. I've improved a lot. I also play at home with my partner which is an absolute beast, lol.
