【问题描述】：

我正在尝试从此模板重新创建数据表：

https://adminlte.io/themes/AdminLTE/pages/tables/data.html

它工作正常，但我缺少用于排序的up and down icons。我不知道他们为什么不出现......

  $(function () {
    $('#example1').DataTable()
    $('#example2').DataTable({
      'paging'      : true,
      'lengthChange': false,
      'searching'   : false,
      'ordering'    : true,
      'info'        : true,
      'autoWidth'   : false
    })
  })

【问题讨论】：

标签： jquery css templates datatables icons

【解决方案1】：

链接到用于显示这些箭头“向上和向下图标”的字体存在问题。

CORS 策略已阻止从源“null”访问“https://adminlte.io/themes/AdminLTE/bower_components/bootstrap/dist/fonts/glyphicons-halflings-regular.ttf”处的字体：请求的资源上不存在“Access-Control-Allow-Origin”标头。因此不允许访问 Origin 'null'。

您可以从here 下载字体文件，然后将其包含在内。之后它应该可以正常工作了。

编辑： 您可以使用支持 glyphicon 的 Bootstrap V.3 而不是下载字体文件。

注意：Bootstrap V4 不支持 glyphicon

将此添加到您的应用中

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="glyphicon glyphicon-sort">Test</div>
<br/>

<div class="glyphicon glyphicon-sort-by-attributes-alt">Test</div>

【讨论】：

你应该使用免费的 cdn cdn.datatables.net/1.10.18/css/dataTables.bootstrap4.min.css
@LegenJerry 我测试了你的代码，但没有成功
@Jarla 我提供了指向您的项目依赖项之一的链接。 CDN 是一个内容交付网络。对依赖项使用 CDN 可以大大减少服务器负载，是最佳实践。我没有提供代码供你测试。
@LegenJerry 我用我的例子测试了你的代码。现在箭头看起来像这样：i.imgur.com/1ZyxmFW.png
但我喜欢箭头看起来像这样：adminlte.io/themes/AdminLTE/pages/tables/data.html
