如何将列插入表格? [英] How do I insert column into table?

问题描述

我有一张桌子，我想在第一行的给定值的左侧和右侧插入一列.您可以在此处查看其演示: http://jsfiddle.net/ismailp/vJvam/1/

I have a table and I'm trying to insert a column to the left and right of a given value on the first row. You can see a demo of it here: http://jsfiddle.net/ismailp/vJvam/1/

<table>
    <tbody>
        <tr>
            <td>tag 1</td>
            <td>tag 2</td>
            <td>tag 3</td>
            <td>tag 4</td>
            <td>tag 5</td>
            <td>tag 6</td>
        </tr>
        <tr>
            <td>Some other value1</td>
            <td>Some other value1</td>
            <td>Some other value1</td>
            <td>Some other value1</td>
            <td>Some other value1</td>
            <td>Some other value1</td>
        </tr>
    </tbody>
</table>

我已经将其用于表中的单行，但不适用于n + 1行. jQuery Guru可以在这里帮助我吗?

I've got it working for a single row in the table but not for n+1 rows. Could some jQuery Guru help me out here?
