Actually i need running total for row and column in same page. I am tried to use nth child function. The below code is working for row running total and now i need to add column total function. can some one help me with this.

   ```
$ (document).ready(function() { $ ("tbody:nth-child(2) tr").each(function(){ var col1 = $ (this).find("td:nth-child(2) span span:nth-child(2)").find("input[type='text']"); var col2 = $ (this).find("td:nth-child(3) span span:nth-child(2)").find("input[type='text']"); var col3 = $ (this).find("td:nth-child(4) span span:nth-child(2)").find("input[type='text']"); setInterval(function(){ var num1 = 0; var num2 = 0; num1 = parseInt(col1.val(),10); num2 = parseInt(col2.val(),10); sum = num1 + num2; if( !isNaN(sum) ) col3.val(parseInt((num1 + num2),10)); },1) }); ```
