设置表列宽度

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。

<table>
  <col width="130">
  <col width="80">
  <tr>
    <th>Month</th>
    <th>Savings</th>
  </tr>
  <tr>
    <td>January</td>
    <td>$100</td>
  </tr>
  <tr>
    <td>February</td>
    <td>$80</td>
  </tr>
</table>

这里有另一种在CSS中实现它的最小方法，即使在不支持的旧浏览器中也能工作:n -child和类似的选择器:http://jsfiddle.net/3wZWt/。

HTML:

<table>
    <tr>
        <th>From</th>
        <th>Subject</th>
        <th>Date</th>
    </tr>
    <tr>
        <td>Dmitriy</td>
        <td>Learning CSS</td>
        <td>7/5/2014</td>
    </tr>
</table>

CSS:

table {
    border-collapse: collapse;
    width: 100%;
}

tr > * {
    border: 1px solid #000;
}

tr > th + th {
    width: 70%;
}

tr > th + th + th {
    width: 15%;
}

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>

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>
