` I exactly don't know where the problem is. First column working good, but second one is not sorting correctly. Somebody please help me why It's not sorting.....
Jquery table not sorting numerically.
The issue is that you are taking the values as string.
var aValue = $(a).find('td').eq(index).text(),
bValue = $(b).find('td').eq(index).text();
instead you need to parse it to a number before doing the comparison.
var aValue = $(a).find('td').eq(index).text(),
bValue = $(b).find('td').eq(index).text();
// something like this to parse it out to number
if(!isNaN(+aValue)) aValue = +aValue;
if(!isNaN(+bValue)) bValue = +bValue;
