ActionScheduler_Abstract_ListTable::get_items_query_filters() – Prepares the SQL to filter rows by the options defined at `$this->filter_by`. Before trusting any data sent by the user it validates that it is a valid option.

ActionScheduler_Abstract_ListTable::get_items_query_offset() – Get prepared OFFSET clause for items query
ActionScheduler_Abstract_ListTable::get_items_query_order() – Prepares the ORDER BY sql statement. It uses `$this->sort_by` to know which columns are sortable. This requests validates the orderby $_GET parameter is a valid column and sortable. It will also use order (ASC|DESC) using DESC by default.
ActionScheduler_Abstract_ListTable::get_items_query_search() – Check if the current request is doing a "full text" search. If that is the case prepares the SQL to search texts using LIKE.
ActionScheduler_Abstract_ListTable::set_items() – Set the data for displaying. It will attempt to unserialize (There is a chance that some columns are serialized). This can be override in child classes for further data transformation.
