I would strongly discourage making your main tableview-owning ViewController conform to UITableViewDataSource and UITableViewDelegate like this, if you want to drive multiple tables.

The fact that you have branching logic in your data source methods like if tableView == self.tableView { is an indication that you have two conjoined twin objects that are trying to get out.

Make two separate data source objects, and let them each focus on one of the two data sets, without any branching like this.
