    <th><? echo strtoupper($value['COLUMN_NAME']) ?></th>

    <? endforeach; ?>
  </tr>
    <?
    $listable = \App\Models\listable::list($table);

    $listable = $listable->fetchAll(\PDO::FETCH_ASSOC);

    $keys = array_keys($listable);

    foreach ($listable as $key => $value) { ?>
    <tr> <?
