Nice solution you have there. But you must define a $screen property inside WP_List_Table class (or its child class) before pagination method is invoked. You want to make the $screen property as WP_Screen instance using this function : $this->screen = get_current_screen(); There you go, and your table is ready to go. Thanks
I just run in the same error when adding extra columns to the default post types. The offending line was the $pagenow check. Quick Edit uses admin-ajax.php so it doesn’t renders the custom columns when it’s done. This doesn’t work: if( ‘edit.php’ == $pagenow && is_admin() ) { add_action( ‘admin_init’, array( $this, ‘init_id_column’ ), 999 … Read more

The idea is … Read more
Your problem is a simple typo: array($this, ‘manage_post_columns’, 10, 2) VS. array($this, ‘manage_post_columns’), 10, 2 I guess you see the difference
If you add a bulk-action, then you have to react on this action. Simply adding a function doesn’t do anything, you have to call it: class WPSE_List_Table extends WP_List_Table { public function __construct() { parent::__construct( array( ‘singular’ => ‘singular_form’, ‘plural’ => ‘plural_form’, ‘ajax’ => false ) ); } public function prepare_items() { $columns = $this->get_columns(); … Read more

I don’t know what you mean by dirty way, hopefully not core editing! You can hide it with CSS. Or you can do it with PHP – see below: Hide the views part You can remove the views part with add_filter( ‘views_edit-post’, ‘__return_null’ ); for the post post type on the edit.php screen. The post … Read more
