如何在表格单元格中使用UIWebView？

let webView = UIWebView(frame: CGRect.zero)
webView.translatesAutoresizingMaskIntoConstraints = false
webView.delegate = self

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)

    // 添加UIWebView实例到单元格中
    cell.contentView.addSubview(webView)

    // 设置UIWebView实例的约束
    let views = ["webView": webView]
    var constraints = NSLayoutConstraint.constraints(withVisualFormat: "H:|[webView]|", options: [], metrics: nil, views: views)
    constraints += NSLayoutConstraint.constraints(withVisualFormat: "V:|[webView]|", options: [], metrics: nil, views: views)
    NSLayoutConstraint.activate(constraints)

    // 加载网页内容
    let url = URL(string: "https://www.example.com")
    let request = URLRequest(url: url!)
    webView.loadRequest(request)

    return cell
}

func webViewDidStartLoad(_ webView: UIWebView) {
    // 开始加载网页时的处理
}

func webViewDidFinishLoad(_ webView: UIWebView) {
    // 完成加载网页时的处理
}

func webView(_ webView: UIWebView, didFailLoadWithError error: Error) {
    // 加载网页出错时的处理
}
