/**
 * Displays a {@link SS_List} in a grid format.
 *
 * GridField is a field that takes an SS_List and displays it in an table with rows and columns.
 * It reminds of the old TableFields but works with SS_List types and only loads the necessary
 * rows from the list.
 *
 * The minimum configuration is to pass in name and title of the field and a SS_List.
 *
 * <code>
 * $gridField = new GridField('ExampleGrid', 'Example grid', new DataList('Page'));
 * </code>
 *
 * Caution: The form field does not include any JavaScript or CSS when used outside of the CMS context,
 * since the required frontend dependencies are included through CMS bundling.
 *
 * @see SS_List
