 If you use the register_column_headers function, it creates a new instance
 of the _WP_List_Table_Compat class.

 _WP_List_Table_Compat::get_column_info() method returns an array with 3
 values. Line 114 file /wp-admin/includes/list-table.php

 WP_List_Table::print_column_headers() method uses the
 $this->get_column_info() method which expects 4 values. Line 993 file
 /wp-admin/includes/class-wp-list-table.php

 Debug returns the fallowing notice
 Notice: Undefined offset: 3 in /wp-admin/includes/class-wp-list-table.php
 on line 993
