在Tableview中，我想知道如何在单元格最后位置设置多行UILabel

import UIKit

class CustomTableViewCell: UITableViewCell {
    var customLabel: UILabel!

    override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)
        
        customLabel = UILabel()
        customLabel.numberOfLines = 0
        customLabel.translatesAutoresizingMaskIntoConstraints = false
        contentView.addSubview(customLabel)
        
        NSLayoutConstraint.activate([
            customLabel.leadingAnchor.constraint(equalTo: contentView.leadingAnchor, constant: 16),
            customLabel.trailingAnchor.constraint(equalTo: contentView.trailingAnchor, constant: -16),
            customLabel.topAnchor.constraint(equalTo: contentView.topAnchor, constant: 8),
            customLabel.bottomAnchor.constraint(equalTo: contentView.bottomAnchor, constant: -8)
        ])
    }
    
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}

class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
    var tableView: UITableView!
    var data: [String] = ["Label 1", "Label 2", "Label 3", "Label 4", "Label 5"]

    override func viewDidLoad() {
        super.viewDidLoad()
        
        tableView = UITableView(frame: view.bounds, style: .plain)
        tableView.dataSource = self
        tableView.delegate = self
        tableView.register(CustomTableViewCell.self, forCellReuseIdentifier: "CustomCell")
        view.addSubview(tableView)
    }
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return data.count
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "CustomCell", for: indexPath) as! CustomTableViewCell
        cell.customLabel.text = data[indexPath.row]
        return cell
    }
}
