swift逆向传参

创建一个表格类是控制器

import UIKit

class TableVC: UITableViewController {
    
    var sectionName:[String] = []
    var rowName1:[String] = []
    var rowName2:[String] = []
    var rowName3:[String] = []
    var rowName4:[String] = []
    
    var cellNum:Int = 0
    
    override func viewDidLoad() {
        super.viewDidLoad()

        self.navigationItem.title = "周考成绩单"
        
        sectionName = ["张三","李四","王五","赵六"]
    
        self.tableView.delegate = self
        self.tableView.dataSource = self
        
        self.tableView.tableFooterView = UIView()
        
        self.navigationItem.leftBarButtonItem = UIBarButtonItem(title: "全部", style: .plain, target: self, action: #selector(whole))
    }
    
    @objc func whole() {
        
        if rowName1.count>0{
            print("张三：\(rowName1[0]),\(rowName1[1]),\(rowName1[2])")
        }
        if rowName2.count>0{
            print("李四：\(rowName2[0]),\(rowName2[1]),\(rowName2[2])")
        }
        if rowName3.count>0{

        }
        if rowName4.count>0{
            print("赵六：\(rowName4[0]),\(rowName4[1]),\(rowName4[2])")
        }
        
       
    }

    // MARK: - Table view data source

    override func numberOfSections(in tableView: UITableView) -> Int {
