<hgroup> or <vgroup> objects. It isn't supported
for <colgroup> objects. Also, you must not set Group.Frame
to True when using this attribute. If you want to set the background color
of a framed group, you have to create a helper group around the group
whose background color you want to set, e.g.
<vgroup frame="true" padding="0">
<vgroup color="#ffffff">
...
</vgroup>
</vgroup>

If you want to set the background color for a <colgroup>, you
can also just create a helper group around the column group (see above).
