I'm trying to figure out if it's possible to style a TD element using the editor's Style dropdown menu.

Currently, I have this style set up in the site's stylesheet:

.TableHeader {
color: #ffffff;
font-size: 1.1em;
font-weight: bold;
background-color: #2f6da1;
}

So then I have this style set up in the XML file:

<Style name="TableHeader" element="td">
<Attribute name="class" value="TableHeader" />
</Style>

Supposedly the editor does support styles for the TD object, but I can't get it to work for the life of me. When I place my cursor in a table cell which does have <td class="TableHeader"> hand-coded in already, the style dropdown will change to read "TableHeader".

However, if I click the Styles dropdown, "TableHeader" is not listed as a choice. This also happens if I try to style a table cell that does not have a style currently applied. Any ideas?????
