In my content type field, I have a select list of current users on the system. I want to create a page that lists all these usernames in a table. The key is the user id (uid). The label is their username. When sorting in Views, it sorts by the key (uid number). I want it to sort by the label (username). Is there a way to do this with Views? Keep in mind that the user list is all dynamically generated so manually reordering is not an option!
