How do I save / load values in a table by using DataStoreService?

Since the table is called tbl, you would just put tbl in the content of your DataStore and it would save the entire table. DataStoreService is complicated, so you may want to check out a guide like this one: Datastore Tutorial for Beginners
Very watered down version, you use game.Players.PlayerAdded and game.Players.PlayerRemoving and connect it to a save and load function.
