extension ViewController {
    override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        return webCellHeight
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withClass: WebViewCell.self, for: indexPath)
        // test url and scriptNames
        cell.setupURLString("https://test.com", delegate: self, isAddObservers: true)
        cell.webView.addScriptMessageHandler(scriptNames: ["test"]) { (_, message) in
