func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    if section == 0 {
        return nil
    } else if settings[section - 1].isEmpty == false {
        let headerView = Bundle.main.loadNibNamed("HeaderTableViewCell", owner: self, options: nil)?.first as! HeaderTableViewCell

        let settingCategories = ["Account", "Notifications", "Personalized Feed", "Color Theme"]

        headerView.settingCategoryTitle.text = settingCategories[section - 1]

        let totalCellHeight = CGFloat(settings[section - 1].count * 63)
        let height = headerView.frame.height + totalCellHeight

        print("Needed Height: \(height)")

        headerView.clipsToBounds = false
        headerView.headerBackground.frame.size.height = height



        print("HeaderView Height: \(headerView.headerBackground.frame.size.height)")

        headerView.headerBackground.layer.shadowRadius = 10
        headerView.headerBackground.layer.shadowOffset = CGSize(width: 0, height: 1)
        headerView.headerBackground.layer.shadowColor = UIColor.black.cgColor
        headerView.headerBackground.layer.shadowOpacity = 0.1
        headerView.headerBackground.backgroundColor = UIColor(named: "Background")
        headerView.headerBackground.layer.cornerRadius = 10

        headerView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleDropDown)))

        return headerView
    } else {
        return nil
    }
}

@objc func handleDropDown() {
    print("Handle Drop Down")
}

func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    if section == 0 {
        return 0.0001
    } else {
        return 54
    }
}

func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
    if section == 0 {
        return 10
    } else {
        return 20
    }
}


func numberOfSections(in tableView: UITableView) -> Int {
    return settings.count + 1
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    if section == 0 {
        return 1
    } else {
        return settings[section - 1].count
    }
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    if indexPath.section == 0 {
        let cell = tableView.dequeueReusableCell(withIdentifier: "SettingTitleCell", for: indexPath) as! SettingsTitleTableViewCell

        cell.titleLabel.text = "Settings"

        return cell
    } else {
        let cell = tableView.dequeueReusableCell(withIdentifier: "SettingCell", for: indexPath) as! SettingTableViewCell

        cell.setSetting(setting: settings[indexPath.section - 1][indexPath.row])
        print("Index Path: \(indexPath.row) SettingCount: \(settings[indexPath.section - 1].count)")


        return cell
    }

}

我做对了吗？我需要在那里导入那些链接，但是我不知道该怎么做错误： Angular Live Development Server正在localhost：4200上侦听，请在http://localhost:4200/ **上打开浏览器 92％的其他资产处理脚本-webpack-plugin×“ wdm”：错误：ENOENT：无此类文件或目录，打开'C：\ ms-front-web @ import http：\ cdnjs.cloudflare.com \ ajax \ libs \ jquery.form \ 3.32 \ jquery.form.js'

似乎不允许在脚本中添加CDN网址，而应该将CDN中的js / css文件包含在index.html中。

<script src="http://cdnjs.cloudflare.com/ajax/libs/jquery.form/3.32/jquery.form.js" />

一些链接供您参考以及如何使用。 Angular include CDN in component usage https://github.com/angular/angular-cli/issues/2280 https://github.com/angular/angular-cli/issues/6887

我建议使用npm将软件包安装为模块，并将其包含在脚本中。

示例： npm install bootstrap --save-dev npm install jquery --save-dev 然后

"scripts": [
    "../node_modules/jquery/dist/jquery.js",
    "../node_modules/bootstrap/dist/js/bootstrap.js"
],

我如何在angular cli项目的脚本部分中添加URL链接
