Lines 191+

        // Add our hidden 'id' column.
        drupal_render($form['example_items'][$id]['id']),
        // Add our hidden 'parent id' column.
        drupal_render($form['example_items'][$id]['pid']),

This will make show-hide rows link work only on pid. Usually we don't want any numerical data displayed to end user, so it should be:

        // Add our hidden 'id' and 'parent' column.
        // Both in one column, because 'Show row weights' will only support one.
        drupal_render($form['example_items'][$id]['id']) .  drupal_render($form['example_items'][$id]['pid']),

And of course in $header we would need to change t('ID'), t('PID') to t('ID & PID')

Or at least describe better why ID does not get hidden.

It seems to me the reason we show ID and PID is so the user can easily see the relationship between them, and also edit the PID. I think the relationship is clearer if they each have their own column in the table.
