    <tr>

        <th class="col label" scope="row"><?= $block->escapeHtml(__($_data['label'])) ?></th>
        <td class="col data" data-th="<?= $block->escapeHtml(__($_data['label'])) ?>"><?= /* @escapeNotVerified */ 
        $_helper->productAttribute($_product, $_data['value'], $_data['code'])

    </tr>
