表格布局表:固定; 以及如何使一个列更宽

Question

所以我有一个这种风格的桌子:

table-layout: fixed;

这使得所有列的宽度相同.我希望有一列(第一列)更宽,然后其余的列占据表的剩余宽度,宽度相等.

怎么实现呢？

table {
  border-collapse: collapse;
  width: 100%;
  border: 1px solid black;
  background: #ddd;
  table-layout: fixed;
}

table th, table td {
  border: 1px solid #000;
}

table td.wideRow, table th.wideRow {
  width: 300px;
}

<table class="CalendarReservationsBodyTable">
  <thead>
    <tr>
      <th colspan="97">Rezervovane auta</th>
    </tr>
    <tr>
      <th class="corner wideRow">Auto</th>
      <th class="odd" colspan="4">0</th>
      <th class="" colspan="4">1</th>
      <th class="odd" colspan="4">2</th>
      <th class="" colspan="4">3</th>
      <th class="odd" colspan="4">4</th>
      <th class="" colspan="4">5</th>
      <th class="odd" colspan="4">6</th>
      <th class="" colspan="4">7</th>
      <th class="odd" colspan="4">8</th>

注意第一列,我希望它是300px宽的.

Answer 1

你可以给第一个单元格(因此列)一个宽度,其余的默认值为 auto

table {
  table-layout: fixed;
  border-collapse: collapse;
  width: 100%;
}
td {
  border: 1px solid #000;
  width: 150px;
}
td+td {
  width: auto;
}

<table>
  <tr>
    <td>150px</td>
    <td>equal</td>
    <td>equal</td>
  </tr>
</table>

或者,获取列宽的"正确方法"可能是使用col元素本身

table {
  table-layout: fixed;
  border-collapse: collapse;
  width: 100%;
}
td {
  border: 1px solid #000;
}
.wide {
  width: 150px;
}

<table>
  <col span="1" class="wide">
    <tr>
      <td>150px</td>
      <td>equal</td>
      <td>equal</td>
    </tr>
</table>

Answer 2

表格布局的重要之处:固定是列宽由表格的第一行决定.

所以

如果您的表结构如下(标准表结构)

<table>
  <thead>
      <tr>
          <th> First column </th>
          <th> Second column </th>
          <th> Third column </th>        
      </tr>
  </thead>

   <tbody>
      <tr>
          <td> First column </td>
          <td> Second column </td>
          <td> Third column </td>        
      </tr>
  </tbody>

如果你想给第二列增加一个宽度

<style> 
    table{
        table-layout:fixed;
        width: 100%;
    }

    table tr th:nth-child(2){
       width: 60%;
     }

</style>

请看,我们的风格不是td.

Answer 3

你在创建一个非常大的表(数百行和列)吗？如果是这样,这table-layout: fixed;是一个好主意,因为浏览器只需要读取第一行以便计算和渲染整个行table,因此加载速度更快.

但如果没有,我会建议倾销table-layout: fixed;和更改您的CSS如下:

table th, table td{
border: 1px solid #000;
width:20px;  //or something similar   
}

table td.wideRow, table th.wideRow{
width: 300px;
}

Answer 4

你可以做的是这样的（伪代码）：

<container table>
  <tr>
    <td>
      <"300px" table>
    <td>
      <fixed layout table>

基本上，将表分成两个表，并将其包含在另一个表中。
