Allow to disable sorting by a specific column

Created by: barmic12

What would you like to be able to do? I was trying to find an option to disable sorting by a specific column (virtual attribute)

How could we go about implementing that? Providing a way (for example by `with_options(sortable: false) to disable sorting

Sometimes there is a need to display virtual attributes - then the sorting does not work. In this case it should not be possible to perform this action (click on the column name). Unfortunately, I didn't find a way to achieve that.
