The WP_List_Table class ultimately uses the single_row_columns method to output each table cell. If we look at that method, we’ll see this part: … elseif ( method_exists( $this, ‘column_’ . $column_name ) ) { echo “<td $attributes>”; echo call_user_func( array( &$this, ‘column_’ . $column_name ), $item ); echo “</td>”; } … Add a method to … Read more
I don’t know if we are allowed to link to other answers but there is another question very similar to yours and the accepted answerer stated these things: You should be skeptical of anyone who says that there is a single “right” way.

Found it, the action needs to be defined in your plugin function: function process_bulk_action() {
$data = $wpdb->get_results($sql, ARRAY_A); Adding ARRAY_A forces get_results to return an associative array.
