表与表布局: 固定; 以及如何使一列更宽

我有一张这样的桌子:

table-layout: fixed;

使所有列的宽度相同。我希望有一个列(第一个)更宽,然后其余的列占据表的剩余宽度与宽度相等。

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>
</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>

注意第一列,我希望它是 300px宽的。

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.

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

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


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

http://jsfiddle.net/6p9K3/1/

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

<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.

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

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.

So

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

<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

<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.
