Re: sum of table rows

It sounds as if this might be a good candidate for my Calculation plug-in:
http://www.pengoworks.com/workshop/jquery/calculation.plugin.htm

$("tr").each(function (){
var sum = $("span.length", this).sum();
var person = $("td.person").text();

alert(person + " = " + sum);
});
