    /*
    Purpose: add custom column header and custom column content to respective custom header in Manage Category Editing Page
    Version Tested: 3.8
    Story:
    Because I found no explanation nor documents in Wordpress.org, I tried to trace the code in wp-admin folder
    after understanding the operation of apply_filter(), add_action() and add_filter()
    Logic:
    The table list in edit_tag.php is based on
    wp-admin/includes/class-wp-list-table.php and
    wp-admin/includes/class-wp-terms-list-table.php
    Note: actually class-wp-terms-list-table.php is creating a class extend the basic table list class in class-wp-list-table.php
