Sorting Problem with Nested Header

When i used nested header then sorting is not working ,how can we manage that,
provide some demo example with sorting with nested header

Like i have table
Name Salary Address
Total

i want to sorting on Name,Salary,Address

when i remove Total Header sorting is working but when i add Total header that time sorting is not working

Hi @zeus2nawaz

column sorting on nested headers work only for the last header level. Like in this example
demo: Handsontable example - JSFiddle - Code Playground

It will work only if you hit a header from N to W.
