css - 带有固定标题的引导表 - Angular 5

Question

我用 HTML 创建了一个表格，我想显示它的标题是固定的(滚动只会影响正文)。

我找到了一个解决方案，它几乎可以正常工作。

tbody {
  display:block;
  height:500px;
  overflow:auto;
}
thead, tbody tr {
  display:table;
  width:100%;
  table-layout:fixed;/* even columns width , fix width of table too*/
}
thead {
  width: calc( 100% - 1em )/* scrollbar is average 1em/16px width, remove it from thead width */
}
table {
  width:400px;
}

问题是使用属性 table-layout: fixed，它固定了列的宽度，所以我的列没有正确显示(它们重叠):

我该如何解决？我已经尝试过 table-layout 的四个可能值

Answer 1

使用td {word-wrap: break-word;}

tbody {
  display:block;
  height:500px;
  overflow:auto;
}
thead, tbody tr {
  display:table;
  width:100%;
  table-layout:fixed;/* even columns width , fix width of table too*/
}
td{
    word-wrap: break-word;
}
thead {
  width: calc( 100% - 1em )/* scrollbar is average 1em/16px width, remove it from thead width */
}
table {
  width:400px;
}

<table class="a">
  <thead>
    <th>Company</th>
    <th>Contact</th>
    <th>Country</th>
  </thead>
  <tbody>
  <tr>
    <td>AlfredsFutterkisteghrtrh</td>
    <td>Maria Anders</td>
    <td>Germany</td>
  </tr>
  <tr>
    <td>Island Trading</td>
    <td>Helen Bennett</td>
    <td>UK</td>
