how to delete an object from an array of objects in multiple objects?

{ "table_id" : 1, "players" : [ { "player_id" : "user1" }, { "player_id" : "user2" }, { "player_id" : "user3" } ] }, { "table_id" : 2, "players" : [ { "player_id" : "user4" }, { "player_id" : "user5" }, { "player_id" : "user6" } ] }
