I'm trying to style a <col> to set the following for a table column:

width:100mm (works in IE7, Firefox and Prince)
background-color: pink (works in IE7, Firefox and Prince)

font-weight:bold (works in IE7, not in FF/Prince)
font-size:32px (works in IE7, not in FF/Prince)
color:red (works in IE7, not in FF/Prince)

Am I doing something wrong, or is it impossible to define most style parameters for a <col>?

BTW, the same seems to apply for <colgroup>.

IE7 is actually wrong in this case, as the properties do not inherit down from the col to the cells, as the cells are not children of the col. This is something that the CSS working group might reconsider in the future though.
