如何以允许用户选择单元格背景颜色的方式在UITableViewCell上获得圆角？(但不使用GROUPED模式)

class CustomTableViewCell: UITableViewCell {
    let customLabel: UILabel = {
        let label = UILabel()
        label.layer.cornerRadius = 10 // 设置圆角半径
        label.layer.masksToBounds = true // 启用圆角
        label.textAlignment = .center
        label.numberOfLines = 1
        return label
    }()
}

class CustomTableViewCell: UITableViewCell {
    let customLabel: UILabel = {
        let label = UILabel()
        label.layer.cornerRadius = 10 // 设置圆角半径
        label.layer.masksToBounds = true // 启用圆角
        label.textAlignment = .center
        label.numberOfLines = 1
        return label
    }()

    let colorButton: UIButton = {
        let button = UIButton()
        button.layer.cornerRadius = 10 // 设置圆角半径
        button.layer.masksToBounds = true // 启用圆角
        button.addTarget(self, action: #selector(colorButtonTapped), for: .touchUpInside)
        return button
    }()

    @objc func colorButtonTapped() {
        // 在这里实现颜色选择器的弹出
    }
}

class CustomTableViewCell: UITableViewCell {
    let customLabel: UILabel = {
        let label = UILabel()
        label.layer.cornerRadius = 10 // 设置圆角半径
        label.layer.masksToBounds = true // 启用圆角
        label.textAlignment = .center
        label.numberOfLines = 1
        return label
    }()

    let colorButton: UIButton = {
        let button = UIButton()
        button.layer.cornerRadius = 10 // 设置圆角半径
        button.layer.masksToBounds = true // 启用圆角
        button.addTarget(self, action: #selector(colorButtonTapped), for: .touchUpInside)
        return button
    }()

    @objc func colorButtonTapped() {
        // 在这里实现颜色选择器的弹出
        let colorPicker = UIColorPickerViewController()
        colorPicker.selectedColor = customLabel.backgroundColor
        colorPicker.delegate = self
        present(colorPicker, animated: true, completion: nil)
    }

    func colorPickerViewControllerDidSelectColor(_ viewController: UIColorPickerViewController) {
        customLabel.backgroundColor = viewController.selectedColor
    }
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "CustomTableViewCell", for: indexPath) as! CustomTableViewCell
    cell.customLabel.text = "Custom Cell"
    cell.colorButton.backgroundColor = cell.customLabel.backgroundColor
    return cell
}
