一直看到很多的地方用到这些自动截断的地方，以前也测试过，但是一直没有十分完美的实现过。手头的项目正好再次需要实现这个效果，这就促使了和同事共同研究这个问题，最终终于完美实现。

以前的代码：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>无标题文档</title>
</head>

<body>
<table width="100%" border="1" class="xTable">
<tr>
    <td width="100">col_1</td>
    <td>col_2</td>
    <td width="120">col_3</td>
    <td width="100">col_4</td>
</tr>
<tr>
    <td>abcdefg</td>
    <td>a b c d e f g h i j k l m n o p q r s t u v w x y z a b c d e f g h i j k l m n o p q r s t u v w x y z a b c d e f g h i j k l m n o p q r s t u v w x y z a b c d e f g h i j k l m n o p q r s t u v w x y z</td>
    <td>abcdefg</td>
    <td>abcdefg</td>
</tr>
</table>
</body>
</html>

显示效果：

增加自动截断的代码：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>无标题文档</title>
<style>
table
{
table-layout:fixed;
}
td
{
text-overflow:ellipsis;
white-space:nowrap;
overflow:hidden;
}
</style>
</head>

<body>
<table width="100%" border="1" class="xTable">
<tr>
    <td width="100">col_1</td>
    <td>col_2</td>
    <td width="120">col_3</td>
    <td width="100">col_4</td>
</tr>
<tr>
    <td>abcdefg</td>
    <td>a b c d e f g h i j k l m n o p q r s t u v w x y z a b c d e f g h i j k l m n o p q r s t u v w x y z a b c d e f g h i j k l m n o p q r s t u v w x y z a b c d e f g h i j k l m n o p q r s t u v w x y z</td>
    <td>abcdefg</td>
    <td>abcdefg</td>
</tr>
</table>
</body>
</html>

显示效果：

学习到的东西：关键就是table-layout:fixed这行，以前每次测试失败的原因就是没有增加这个属性。
