【问题描述】：
当单元格被点击到 detailTableView 时，我正在尝试从 tableView 传递数据。加载详细信息表视图时，我没有收到任何错误。 segue 正在执行，但是 tableView 保持空白。我的目标是将颜色添加到单元格中的 textLabel 中，并将 zord 添加到同一单元格中的 detailTextLabel 中。谁能告诉我我做错了什么
// My data
struct PowerRangerData {
let name: String
let rangerColor: String
let zord: String
}
// Intial vc
class DisplayVC: UIViewController {
@IBOutlet weak var table_View: UITableView!
var rangerArray = [
PowerRangerData(name: "Jason", rangerColor: "Gold ranger", zord: "Pyramidas Zord"),
PowerRangerData(name: "Tommy", rangerColor: "Green ranger", zord: "Dragon Zord"),
PowerRangerData(name: "Nick", rangerColor: "Red ranger", zord: "Phoenix Zord"),
PowerRangerData(name: "Kira", rangerColor: "Yellow ranger", zord: "Pteranodon Zord"),
PowerRangerData(name: "Jen", rangerColor: "Pink ranger", zord: "Time flyer 5"),
PowerRangerData(name: "Sky", rangerColor: "Blue ranger", zord: "Delta Runner 2")
]
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "detailSegue" {
if let index_path = self.table_View.indexPathForSelectedRow {
let detailVC = segue.destination as! DetailVC
detailVC.color = rangerArray[index_path.row].rangerColor
detailVC.zord = rangerArray[index_path.row].zord
}
}
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
table_View.deselectRow(at: indexPath, animated: true)

}
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return rangerArray.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

cell.textLabel?.text = rangerArray[indexPath.row].name
