We are using a table structure and want to Auto SUM the cells that are highlighted.

Similar to this

<table>
<tr>
<td>3</td>
<td>4</td>
<td>5</td>
</tr>
</table>

If the user highlights columns 1 and 2 a DIV will do the calculation and return 7.  If the user selects the entire row it will return 12 in the corner DIV.

Any thoughts on how to do this?

Thanks in advance...!

Hi, see the working example here: http://jsfiddle.net/robert_schutt/EyD3J/ 

You can click on the individual cells or the row/column headers and selection will toggle, total will be calculated with each change.

The generated jsFiddle code for reference:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<title> - jsFiddle demo by robert_schutt</title>
<script type='text/javascript' src='http://code.jquery.com/jquery-git.js'></script>
<style type='text/css'>
.sel {
    background-color: red;
}
.tot {
    float: right;
    border: 2px solid green;
}
</style>
<script type='text/javascript'>//<![CDATA[ 
$(window).load(function(){
$('td').on('click', function(){
    $(this).toggleClass('sel');
    calcTot();
});
$('tr:first th').on('click', function(){
    $('tr:not(:first) td:nth-child('+($(this).index()+1)+')').toggleClass('sel');
    calcTot();
});
$('tr:not(:first) th').on('click', function(){
    $(this).closest('tr').find('td').toggleClass('sel');
    calcTot();
});

function calcTot() {
    var tot = 0;
    $('td.sel').each(function(){
        tot += 1 * $(this).text();
    });
    $('div.tot').html(tot);
}
});//]]>  
</script>
</head>
<body>
<table border="1">
<tr>
<th></th>
<th>col 1</th>
<th>col 2</th>
<th>col 3</th>
</tr>
<tr>
<th>row 1</th>
<td>3</td>
<td>4</td>
<td>5</td>
</tr>
<tr>
<th>row 2</th>
<td>13</td>
<td>14</td>
<td>15</td>
</tr>
</table>
<div class="tot">
</div>
</body>
</html>
