Comment:

 When the array() argument is removed from line 24 (see screen.diff
 attachment), the table does tabulate properly without the need of
 initializing the WP_List_Table class before the page is loaded using
 add_action( "load-$screen_id", array( $this, '_init_list_table' ) ) as
 recommended in my-list-table-plugin.php above. The WP_List_table class can
 be initialized inside the function that was declared for add_menu_page().

 Then I would be able to dynamically render different tables according to
 the GET variable. Useful for tabbed pages.

 I was wondering since get_columns() do not require an input argument,
 maybe we could remove array() from line 24?
