Why doesn't my first HTML table column have bold text?

Question

My understanding of the col tag tells me that the following should style text in my first table column as bold, but this is not happening. What am I doing wrong?

<table class="span-12">
    <col style="font-weight: bold;" />
    <col />
    <tr>
        <td>
            Client
        </td>
        <td>
            Apartment Applied Visual Arts
        </td>
    </tr>
</table>

Answer 1

The table data cells are not descendants of the col element, so they do not inherit any properties from it. See the columns section of the CSS specification.
