How to repair a crack in my firepit?

My fire pit has a crack from side to side on the table top portion. The crack meets evenly with a small gap. Someone had tried to repair it using some sort of glue product. I was considering putting tile or stones over it but don’t have a clue how to seal the crack so it won’t break again. Help please. Thank you
