如何使用可滚动的表格主体应用宽度 100%

Question

我正在尝试实现表体可滚动。我能够成功地做到这一点，但现在我面临宽度 100% 的问题

请检查这个 jsfiddle https://jsfiddle.net/Ratan_Paul/stpgd6x6/

<table>
<thead style="display:block;">
  <tr>
    <th>Company</th>
    <th>Contact</th>
    <th>Country</th>
  </tr>
 </thead>
 <tbody style="max-height: 50px;display: block;overflow-y:auto;">
  <tr>
    <td>Alfreds Futterkiste</td>
    <td>Maria Anders</td>
    <td>Germany</td>
  </tr>
  <tr>
    <td>Centro comercial Moctezuma</td>
    <td>Francisco Chang</td>
    <td>Mexico</td>
  </tr>
  <tr>
    <td>Ernst Handel</td>
    <td>Roland Mendel</td>
    <td>Austria</td>
  </tr>
  <tr>
    <td>Island Trading</td>
    <td>Helen Bennett</td>
    <td>UK</td>
  </tr>
  <tr>
    <td>Laughing Bacchus Winecellars</td>
    <td>Yoshi Tannamuri</td>
    <td>Canada</td>
  </tr>
  <tr>
    <td>Magazzini Alimentari Riuniti</td>
    <td>Giovanni Rovelli</td>
    <td>Italy</td>
  </tr>
  </tbody>
</table>

我不能将宽度应用于 thead 和 tbody 吗？任何解决方案，这样我就可以使用滚动并将宽度设置为 100%

Answer 1

有一个更简单的 CSS 解决方案。不用担心元素的宽度和滚动，用容器 div 包裹表格并将样式 position: sticky 用于 th 元素。下面的示例 sn-p -

.table-container {
  max-height: 160px;
  border: 1px solid red;
  overflow: auto;
}

th {
  position: sticky;
  top: 0;
  background: white;
}

td, th {
  padding: 4px 8px;
}

<div class="table-container">
  <table>
    <thead>
      <tr>
        <th>Company</th>
        <th>Contact</th>
        <th>Country</th>
      </tr>
    </thead>
    <tbody>
      <tr>
        <td>Alfreds Futterkiste</td>
        <td>Maria Anders</td>
        <td>Germany</td>
      </tr>
      <tr>
        <td>Centro comercial Moctezuma</td>
        <td>Francisco Chang</td>
        <td>Mexico</td>
      </tr>
      <tr>
        <td>Ernst Handel</td>
        <td>Roland Mendel</td>
        <td>Austria</td>
      </tr>
      <tr>
        <td>Island Trading</td>
        <td>Helen Bennett</td>
        <td>UK</td>
      </tr>
      <tr>
        <td>Laughing Bacchus Winecellars</td>
        <td>Yoshi Tannamuri</td>
        <td>Canada</td>
      </tr>
      <tr>
        <td>Magazzini Alimentari Riuniti</td>
        <td>Giovanni Rovelli</td>
        <td>Italy</td>
      </tr>
    </tbody>
  </table>
</div>

Answer 2

如果您想让表格可滚动并设置它的高度，您只需使用表格本身。

删除表格上的所有样式，并添加以下 css：

table {
  width: 100%;
  max-height: 80px;
  display: block;
  overflow-y: scroll;
  position: relative;
}

试试这个代码。我认为这对你来说是最好的

table{
  width:100%;
}
tbody{
  width:100% !important;
  max-height: 50px;
  display: block;
  overflow-y:auto;
}
thead{
  min-width:100% !important;
}
thead tr{
  width:calc(100% - 17px) !important;
  display:inline-block;
}
tbody tr{
  width:100% !important;
  display:inline-block;
}
th, td{
  width:30% !important;
  display:inline-block;
  text-align:left;
}

<table>
<thead>
  <tr>
    <th>Company</th>
    <th>Contact</th>
    <th>Country</th>
  </tr>
 </thead>
 <tbody>
  <tr>
    <td>Alfreds Futterkiste</td>
    <td>Maria Anders</td>
    <td>Germany</td>
  </tr>
  <tr>
    <td>Centro comercial Moctezuma</td>
    <td>Francisco Chang</td>
    <td>Mexico</td>
  </tr>
  <tr>
    <td>Ernst Handel</td>
    <td>Roland Mendel</td>
    <td>Austria</td>
  </tr>
  <tr>
    <td>Island Trading</td>
    <td>Helen Bennett</td>
    <td>UK</td>
  </tr>
  <tr>
    <td>Laughing Bacchus Winecellars</td>
    <td>Yoshi Tannamuri</td>
    <td>Canada</td>
  </tr>
  <tr>
    <td>Magazzini Alimentari Riuniti</td>
    <td>Giovanni Rovelli</td>
    <td>Italy</td>
  </tr>
  </tbody>
</table>

Answer 4

您需要清除表格最初附带的一些样式，并将宽度设置为 33%，因为您使用的是 3 个列标题 (100%/3)

见下文：

table {
    width: 100%;
    border-collapse: collapse;
    border-spacing: 0;
    border: 2px solid black;
}

thead, tbody, tr, td, th { display: block; }

tr:after {
    content: ' ';
    display: block;
    visibility: hidden;
    clear: both;
}

thead th { 
    height: 30px;
    line-height: 30px;
    text-align: left;
}

tbody {
    height: 100px;
    overflow-y: auto;
}

thead {
    /* fallback */
    width: 97%;
    /* minus scroll bar width */
    width: calc(100% - 17px);
}

tbody { border-top: 2px solid black; }

tbody td, thead th {
    width: 33%;
    float: left;
}

tbody td:last-child, thead th:last-child {
    border-right: none;
}

<table>
<thead>
  <tr>
    <th>Company</th>
    <th>Contact</th>
    <th>Country</th>
  </tr>
 </thead>
 <tbody>
  <tr>
    <td>Alfreds Futterkiste</td>
    <td>Maria Anders</td>
    <td>Germany</td>
  </tr>
  <tr>
    <td>Centro comercial Moctezuma</td>
    <td>Francisco Chang</td>
    <td>Mexico</td>
  </tr>
  <tr>
    <td>Ernst Handel</td>
    <td>Roland Mendel</td>
    <td>Austria</td>
  </tr>
  <tr>
    <td>Island Trading</td>
    <td>Helen Bennett</td>
    <td>UK</td>
  </tr>
  <tr>
    <td>Laughing Bacchus Winecellars</td>
    <td>Yoshi Tannamuri</td>
    <td>Canada</td>
  </tr>
  <tr>
    <td>Magazzini Alimentari Riuniti</td>
    <td>Giovanni Rovelli</td>
    <td>Italy</td>
  </tr>
  </tbody>
</table>
