You can repair the split, but I would use a good quality wood glue rather than gorilla glue. My experience with the Gorilla stuff is that, while it has a tenacious bond, it foams on application and tends to not form the clean “invisible” line of a good carpenter glue. Its wood, and its a forgiving material.
The finish is going to need to be re-applied, and chances are you will need to remove the old finish, sand to level, and stress the table-top to match the stress of your fall. In other words, you may need to hit it with some chain or other antiquing method to match the gravel damage.
Sorry this happened to you, and hope you are well.
