I need to add a column on the user admin table that shows an icon indicating whether or not the user has confirmed their email address. The user meta field "confirm_code" only exists if they have not confirmed their email address yet. I don't want to display the actual confirmation code on the users table. I just want to display one icon if "confirm_code" exists or a different icon if "confirm_code" does not exist.
Any ideas on how to accomplish this? Thanks
