I am new in wordpress if someone will help me I will be very appreciate.
There is parameter ajax "true" but in docs. wasn't said how to implement Ajax using WP_List_Table Class?
parent::__construct( array(
'singular' => 'user', //singular name of the listed records
'plural' => 'users', //plural name of the listed records
'ajax' => true //does this table support ajax?
) );
