Users table in admin: make role column sortable

You’ll need to use PHPmyAdmin to sort the column. So you’ll need to write a query to do so. If you’re writing it into the php code you can do something similar to this example in the link:

Basically, you’ll need to use the SORT BY statement in your query.
