Class: AC\Column\CustomField

The AC\Column\CustomField class contains the properties, options, and methods of a custom field column. The class extends both the AC\Column\Meta class and the AC\Column class and inherits all its methods.

The main scenario where you might want to use AC\Column\CustomField is when you have been using a filter or action to hook into Admin Columns and one of the callback values is a Custom Field column object.
