你可能想看看:first-child伪类（W3C定义）--这正是它设计的目的，你可以这样使用它：

.table td {
    text-align: right;
}

.table td:first-child {
    text-align: left;
}​

:first-child伪类意味着选择器只匹配每个<tr>中的第一个<td>。
示例如下：http://jsfiddle.net/xv5Cn/1/

您需要指定以下CSS：

.table td,
.table th
{
    text-align:left;
}

#right,
.table td + td,
.table th + th
{
    text-align:right;
}

An example is at JSFiddle .
您可以在 *5.7相邻同级选择器 * 阅读更多关于相邻同级CSS选择器的信息。

您所需要做的就是向要对齐的添加一个类，然后像摆弄一样添加CSS。
