Code

public function submitForm(array &$form, FormStateInterface $form_state) {
    // Because the form elements were keyed with the item ids from the database,
    // we can simply iterate through the submitted values.
    $submissions = $form_state->getValue('table-row');
    foreach ($submissions as $id => $item) {
        $this->database
            ->update('tabledrag_example')

            'weight' => $item['weight'],
            'pid' => $item['pid'],
            'description' => $item['description'],
