Table with table-layout: fixed; and how to make one column wider

htmlcssxhtml

提问by Richard Knop

So I have a table with this style:

所以我有一张这种风格的桌子:

table-layout: fixed;

Which makes all columns to be of the same width. I would like to have one column (the first one) to be wider and then rest of the columns to occupy the remaining width of the table with equal widths.

这使得所有列的宽度相同。我想让一列(第一列)更宽,然后其余的列以相同的宽度占据表格的剩余宽度。

How to achieve that?

如何做到这一点?

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>

Notice the first column, I want it to be 300pxwide.

注意第一列,我希望它很300px宽。

You could just give the first cell (therefore column) a width and have the rest default to auto

你可以只给第一个单元格(因此是列)一个宽度,其余的默认为 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>



or alternatively the "proper way" to get column widths might be to use the colelementitself

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>

The important thing of table-layout: fixed is that the column widths are determined by the first row of the table.

table-layout: fixed 的重要一点是列宽由表格的第一行决定。

So

所以

if your table structure is as follow (standard table structure)

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>

if you would like to give a width to second column then

如果你想给第二列一个宽度

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

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

</style>

Please look that we style the th not the td.

请注意我们的风格不是 td。

Are you creating a very large table (hundreds of rows and columns)? If so, table-layout: fixed;is a good idea, as the browser only needs to read the first row in order to compute and render the entire table, so it loads faster.

您是否正在创建一个非常大的表(数百行和数百列)?如果是这样,这table-layout: fixed;是个好主意,因为浏览器只需要读取第一行即可计算和渲染整个table,因此加载速度更快。

But if not, I would suggest dumping table-layout: fixed;and changing your css as follows:

但如果没有,我建议table-layout: fixed;按如下方式转储和更改您的 css:

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

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

What you could do is something like this (pseudocode):

你可以做的是这样的(伪代码):

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

Basically, split up the table into two tables and have it contained by another table.

基本上,将表拆分为两个表并将其包含在另一个表中。
