[jQuery] Can I select <col> and/or <colgroup>?

[jQuery] Can I select <col> and/or <colgroup>?


I've got a table in which I've set up some column groups.
<colgroup class="location">
<col></col>
</colgroup>
<colgroup class="year">
<col class="this"></col>
<col class="that"></col>
<col class="that"></col>
<col class="that"></col>
</colgroup>
<colgroup class="year">
<col class="this"></col>
<col class="that"></col>
<col class="that"></col>
<col class="that"></col>
</colgroup>
...
Ideally, I'd like to be able to toggle the visibility of the <col
class="that"> - can I select them as cols in jquery, or do I need to
get at them via the rows?
Thanks!
