如何用Swift在iOS中制作一个对角线UITableView？

override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
    super.init(style: style, reuseIdentifier: reuseIdentifier)
    
    self.backgroundColor = UIColor.clear
    self.contentView.backgroundColor = UIColor.clear
    self.selectionStyle = .none
}

required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}

let diagonalView = UIView()

override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
    super.init(style: style, reuseIdentifier: reuseIdentifier)
    
    // ...
    
    diagonalView.backgroundColor = UIColor.white
    self.contentView.addSubview(diagonalView)
}

override func layoutSubviews() {
    super.layoutSubviews()
    
    diagonalView.frame = CGRect(x: 0, y: 0, width: self.contentView.frame.width, height: self.contentView.frame.height)
    
    let path = UIBezierPath()
    path.move(to: CGPoint(x: 0, y: 0))
    path.addLine(to: CGPoint(x: self.contentView.frame.width, y: self.contentView.frame.height))
    path.addLine(to: CGPoint(x: self.contentView.frame.width, y: 0))
    path.close()
    
    let shapeLayer = CAShapeLayer()
    shapeLayer.path = path.cgPath
    diagonalView.layer.mask = shapeLayer
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return 10 // 根据需要返回行数
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "DiagonalTableViewCell", for: indexPath) as! DiagonalTableViewCell
    
    // 配置cell的内容
    
    return cell
}
