Not able to apply sorting for each column individually without affecting other columns

prats

Hi.
when we click any column header, either data get sorted by asc or desc manner and simultaneously ordered data from other columns which is default functionality of data table .
But i want data to be sorted based on individual column.
I have attached my html file which contains columns such as No,name,position,Office....
Scenario that i want to implement is,if we click No. column it will sort data it contains but the rest of data from different columns should not get change.that should remain as it is.

Suppose,
i want to display data from Office Edinburgh that will show all data related to Edinburgh now next to this i want to order the data from position or name column in asc or desc manner individually with keeping office Edinburgh .It may be most likely to sort function in excel...
