sortedtable=varfun(@sortrows,KsTable,'GroupingVariables',{'k_name'});

The table before using sortrow:

after using sortrow:

I do not see an option to override that. However you can

sortedtable.Properties.VariableNames =   KsTable.Properties.VariableNames;

@ Walter Roberson: Yeah it was strange to me why adding sortrow to all file names.

As there are many columns in the table, it is not efficient to do one by one that's why I asked here.
