如何在Firefox中使用和CSS将填充应用于列？

Example:

<style type="text/css">
    table {
        border: 1px solid red;
        border-collapse: collapse;
        text-align: left;
    }
    #col-1 {
        padding-left: 20px;
        background-color: tan;
    }
    #specific-cell {
        padding-left: 20px;
    }
</style>
<table>
    <col id="col-1">
    <col id="col-2">
    <tr>
        <th>foo</th>
        <th>bar</th>
    </tr>
    <tr>
        <td>data1</th>
        <td>data2</th>
    </tr>
    <tr>
        <td id="specific-cell">data1</th>
        <td>data2</th>
    </tr>
    <tr>
        <td>data1</th>
        <td>data2</th>
    </tr>
</table>
<style type="text/css">
    table {
