func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        
    //  Determine what to do when a cell in a particular section is selected.
        switch indexPath.section {
        case 0:
        //  If the cell in the first section is selected, this will trigger the segue with the "toHeightForRowAt" identifier
            self.performSegue(withIdentifier: "toHeightForRowAt", sender: nil)
        case 1:
        //  Create an alert if the cell in the "Managing Selections" section is selected.
            let alert = UIAlertController(title: "Alert", message: "This alert is fired when you select the didSelectRowAt cell.", preferredStyle: .alert)
        //  Create an action do dismiss the Alert Controller.
            alert.addAction(UIAlertAction(title: "Dismiss", style: .default, handler: nil))
            
        //  Create an action that triggers a segue with the identifier "toDidSelectRowAt". That's how you got to this web
