What kind of Tarot tablecloth is better? Can I use what Taobao sells?

Don't worry too much about this. The tablecloth is to prevent the card from being worn by excessive friction with the desktop.

So just use a black cloth, and then be softer, but don't use a slip cloth like silk.

Also be careful not to use reflective cloth as much as possible, because reflective cloth is dazzling and it is not easy to concentrate.
