WCAG enhacement

This is valid when Windows narrator is active.
When you change the sorting order of colum
aria-live will be feeded using the "name" field from colum definition and then will append the ascending/descending word.
Problem is that most of time "name" attribute comes with camel case, underscore, hyphens u other tipe of not friendly for speach characters.
It would be great if we can use "label" field to feed the aria-live.

## Expected Behavior
Aria-live should use "label" field instead of "name".

## Current Behavior
"name" field is used to feed aria-live component.

## Steps to Reproduce (for bugs)
Turn on narrator.
Click on any sortable column header and hear the phrase:
"table is now sorted by [here it is the name field...]"

Hope to be clear.
