    A number of years ago (in the IE only days) I was using the <col align="right"> tag, but I just tested it and and it seems to be an IE only feature:

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
    "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
    <title>Test</title>
</head>
<body>
    <table width="100%" border="1">
        <col align="left" />
        <col align="left" />
        <col align="right" />
        <tr>
            <th>ISBN</th>
            <th>Title</th>
            <th>Price</th>
        </tr>
        <tr>
            <td>3476896</td>
            <td>My first HTML</td>
            <td>$53</td>
        </tr>
    </table>
</body>
</html>

    The snippet is taken from www.w3schools.com. Of course, it should not be used (unless for some reason you really target the IE rendering engine only), but I thought it would be interesting to mention it.

    Edit:

    • IE still supports it.
    • Firefox has dropped support in 3.5.
    • Safari does not seem to support it, but the documentation indicates otherwise.

    Overall, I don't understand the reasoning behing abandoning this tag. It would appear to be very useful (at least for manual HTML publishing).

    The <colgroup> and <col> tags that lives inside tables are designed for this purpose. If you have three columns in your table and want to align the third, add this after your opening <table> tag:

     <colgroup>
     <col />
     <col />
     <col class="your-right-align-class" />
 </colgroup>

    along with the requisite CSS:

     .your-right-align-class { text-align: right; }

    From the W3:

    Definition and Usage

    • The <col> tag defines attribute values for one or more columns in a table.

    • The <col> tag is useful for applying styles to entire columns, instead of repeating the styles for each cell, for each row.

    If it's always the third column, you can use this (assuming table class of "products"). It's kinda hacky though, and not robust if you add a new column.

    table.products td+td+td {
  text-align: right;
}
table.products td,
table.products td+td+td+td {
  text-align: left;
}

    But honestly, the best idea is to use a class on each cell. You can use the col element to set the width, border, background or visibility of a column, but not any other properties. Reasons discussed here.

    What you really want here is:

    <col align="right"/>

    but it looks like Gecko doesn't support this yet: it's been an open bug for over a decade.

    (Geez, why can't Firefox have decent standards support like IE6?)

    This doesn't work in IE6, which may be an issue, but it'll work in IE7+ and Firefox, Safari etc. It'll align the 3rd column right and all of the subsequent columns left.

    td + td + td { text-align: right; }
td + td + td + td { text-align: left; }
