Spaces between table rows with borders in CSS

I'm trying to display a table where each table row has a rounded border. I'm looking to add spaces between these borders and not within the row itself. Originally, I had an additional row <tr class='spacer'> in between each row to space them out, but have since added sorter functionality to my table using a jQuery plugin, Tablesorter.

When I try to sort my table, these spacers sort to the bottom or top, removing the spacing between each row.

What I'm looking for is a way to space between each of these rows and still allow the table to be sortable.

//HTML Follows//

<html>
<head> 
<link rel="stylesheet" type="text/css" href="table.css"/>
<script type="text/javascript" src="jquery.js"></script> 
<script type="text/javascript" src="jquery.tablesorter.min.js"></script> 

<script type="text/javascript">
$(document).ready(function() { 
    $("table").tablesorter(); 
}); 
</script>

</head>

<body>

<table class="tablesorter" cellspacing=0>
<thead> 
    <tr>
    <th>Name</th>
    <th>Date</th>
    <th>Price</th>
</tr>
</thead>

<tbody>
<tr>
    <td class='roundleft'>Keanan</td>
    <td class='spacer'>01/11/11 6:52 AM</td>
    <td class='roundright'>$20.95</td>
</tr>

<tr>
    <td class='roundleft'>Conor</td>
    <td class='spacer'>01/11/11 4:52 PM</td>
    <td class='roundright'>$200.00</td>
</tr>

<tr>
    <td class='roundleft'>Ryan</td>
    <td class='spacer'>01/11/11 12:52 PM</td>
