[jQuery] Styling the 2nd table tag above a row

Hi,
I'm having a dilemma where I need to style the table which encloses a
table with a row which has a style attached to it.
The source looks like this.
<table>
<tbody>
<tr>
<td>
<table>
<tbody>
<tr class="myClass">
etc.
I want to be able to directly access the first table tag to style the
entire table with a border. Is there an easy way to do this in jQuery?
Thanks,
Guy Davis
