We need to understand the Nodes that which are going to add up like First, Last,Last Child or First child something like.
Once you understand the basic logic in which we are going to perform he operation we can do with the following code as an example.

$("#sum_table tr:last td:not(:first)").text(function(i){

var t = 0;
t += parseInt( $(this).text(), 10 ) || 0;
return "Total: " + t;

In the above example I have taken last values for adding. So based on your requirement you should change the logic.
