我有一个简单的表格，用于收件箱如下:
<table border="1">
<tr>
<th>From</th>
<th>Subject</th>
<th>Date</th>
</tr>
</table>
我如何设置宽度，使日期和日期是页面宽度的15%，主题是70%。我还想让表格占据整个页面宽度。

取决于你的主体(或div包装你的表)'settings'你应该能够这样做:
body {
width: 98%;
}
table {
width: 100%;
}
th {
border: 1px solid black;
}
th.From, th.Date {
width: 15%;
}
th.Date {
width: 70%;
}
<table>
<thead>
<tr>
<th class="From">From</th>
<th class="Subject">Subject</th>
<th class="Date">Date</th>
</tr>
</thead>
<tbody>
<tr>
<td>Me</td>
<td>Your question</td>
<td>5/30/2009 2:41:40 AM UTC</td>
</tr>
</tbody>
</table>

这是我的两点建议。
Using classes. There is no need to specify width of the two other columns as they will be set to 15% each automatically by the browser. table { table-layout: fixed; } .subject { width: 70%; } <table> <tr> <th>From</th> <th class="subject">Subject</th> <th>Date</th> </tr> </table> Without using classes. Three different methods but the result is identical. a) table { table-layout: fixed; } th+th { width: 70%; } th+th+th { width: 15%; } <table> <tr> <th>From</th> <th>Subject</th> <th>Date</th> </tr> </table> b) table { table-layout: fixed; } th:nth-of-type(2) { width: 70%; } <table> <tr> <th>From</th> <th>Subject</th> <th>Date</th> </tr> </table> c) This one is my favourite. Same as b) but with better browser support. table { table-layout: fixed; } th:first-child+th { width: 70%; } <table> <tr> <th>From</th> <th>Subject</th> <th>Date</th> </tr> </table>
另一种方法是只使用一个类，同时将样式保存在CSS文件中，即使在IE7中也能工作:
<table class="mytable">
<tr>
<th>From</th>
<th>Subject</th>
<th>Date</th>
</tr>
</table>
<style>
.mytable td, .mytable th { width:15%; }
.mytable td + td, .mytable th + th { width:70%; }
.mytable td + td + td, .mytable th + th + th { width:15%; }
</style>
最近，您还可以使用CSS3 (IE9+)中的n -child()选择器，在那里您只需将各自列的nn .放入括号中，而不是将它们与相邻选择器串在一起。比如这样:
<style>
.mytable tr > *:nth-child(1) { width:15%; }
.mytable tr > *:nth-child(2) { width:70%; }
.mytable tr > *:nth-child(3) { width:15%; }
</style>
style="column-width:300px;white-space: normal;"
取决于你的主体(或div包装你的表)'settings'你应该能够这样做:
body {
width: 98%;
}
table {
width: 100%;
}
th {
border: 1px solid black;
}
th.From, th.Date {
width: 15%;
}
th.Date {
width: 70%;
}
<table>
<thead>
<tr>
<th class="From">From</th>
<th class="Subject">Subject</th>
<th class="Date">Date</th>
</tr>
</thead>
<tbody>
<tr>
<td>Me</td>
<td>Your question</td>
<td>5/30/2009 2:41:40 AM UTC</td>
</tr>
</tbody>
</table>
