数据库 Jquery - 使用 ScrollY 时列标题未对齐

Question

我正在使用 jQuery 的 DataTables 和 Bootstrap。所以我遇到的问题是，当我在“已完成”和“死”选项卡之间切换时，“死”选项卡的列标题会在左侧聚集在一起，直到我单击它们然后它们正确对齐。每当我刷新时都会发生这种情况。我尝试将 CSS 与 overflow:auto 一起使用，但这会使我的整个面板可滚动，这是我不想要的。我希望在滚动表格时标题保持固定。

  <div class = 'row'>
  <div class='col-lg-11'>

  <div id="pane3" > 
  <ul class="nav nav-tabs">
    <li class="active">
      <a  href="#4a" data-toggle="tab">My Completed</a>
    </li>
    <li>
      <a  href="#4b" id="deadTab"  data-toggle="tab">Dead Requests</a>
    </li>

  </ul>
  <div class="tab-content">
      <div class='tab-pane active' id ="4a">
        <!-- <div id="" style=" width: 100%; position:relative; height:200px;"> -->
          <table id='completed' class="table table-striped table-hover">

Answer 1

问题是您的另一个选项卡已隐藏 (display: none)。您可以在dead 选项卡显示如下后初始化您的数据表：

$('#completed').DataTable({
  "paging": false,
  // "fixedHeader": true,
  "scrollY": "140px",
  "table-layout": "fixed",
  "columnDefs": [{
      "width": 60,
      "targets": 0
    },
    {
      "width": 60,
      "targets": 1
    },
    {
      "width": 60,
      "targets": 2
    },
    {
      "width": 60,
      "targets": 3
    },
    {
      "width": 90,
      "targets": 4
    },
    {
      "width": 90,
      "targets": 5
    },
    {
      "width": 90,
      "targets": 6
    },
    {
      "width": 90,
      "targets": 7
    },
  ]

});






$('#deadTab').one('shown.bs.tab', function(e) {
  $('#dead').DataTable({
    "paging": false,
    "fixedHeader": true,
    "scrollY": "140px",
    "table-layout": "fixed",
    "columnDefs": [{
        "width": 60,
        "targets": 0
      },
      {
        "width": 60,
        "targets": 1
      },
      {
        "width": 60,
        "targets": 2
      },
      {
        "width": 60,
        "targets": 3
      },
      {
        "width": 90,
        "targets": 4
      },
      {
        "width": 90,
        "targets": 5
      },
      {
        "width": 90,
        "targets": 6
      },
      {
        "width": 90,
        "targets": 7
      },
    ]

    // "table-layout":"fixed"

  });
})
