设置表列宽 [英] Setting table column width

问题描述

我有一个用于收件箱的简单表格，如下所示：

I've got a simple table that is used for an inbox as follows:

<table border="1">
        <tr>
            <th>From</th>
            <th>Subject</th>
            <th>Date</th>
        </tr>

如何设置宽度，使From和Date为页面宽度的15％是70％。我还希望表格占据整个页面宽度。

How do I set the width so the From and Date are 15% of the page width and the Subject is 70%. I also want the table to take up the whole page width.

推荐答案

<table>
    <colgroup>
       <col span="1" style="width: 15%;">
       <col span="1" style="width: 70%;">
       <col span="1" style="width: 15%;">
    </colgroup>
    <!-- Put <thead>, <tbody>, and <tr>'s here! -->
</table>
