在Drupal 8中,渲染Tables仍然很像Drupal7。您在PHP中构建了行和列的多维数组,然后将Drupal 分别转换为a <tr>
和<td>
s。仍然存在令人困惑的Drupalism,'data'
它使您可以将渲染数组元素添加为单元格数据(不要与数据属性相混淆)。
我得到了一个站点,开发人员选择使用“数据”来渲染单元格的内容,但是我无法弄清楚如何<td>
在数据周围添加类。
我已经阅读了Table.php的源代码和文档,并且知道新版本,#wrapper_attributes
但是我无法破解。
我尝试了至少四种添加类的方法,但均无效果。
$table['row-' . $row_id] = [
// Option 1: Class appears on <tr> tag
'#attributes' => [
'class' => ['option-1-row-attributes'],
'id' => 'row-' . $row_id,
'no_striping' => TRUE,
],
// Option 2: Class appears on <td> tag of first column.
'item' => [
'#markup' => $row['my_item']->label(),
'#wrapper_attributes' => [
'class' => ['option-2-markup-wrapper-attributes'],
],
],
// In the following section, the only item that works is
// the class on the <a> tag.
'edit_operation' => [
'data' => [
'#type' => 'link',
'#url' => Url::fromRoute('my_module.my_route', ['item' => $row_id]),
'#title' => $this->t('Edit'),
'#attributes' => [
// Option 3: Class appears on the anchor tag
'class' => ['use-ajax', 'option-3-link-attributes'],
'data-dialog-type' => 'modal',
'data-dialog-options' => Json::encode([
'width' => 700,
]),
],
// Option 4: Has no effect.
'#wrapper_attributes' => [
'class' => ['option-4-data-wrapper-attributes'],
],
],
// Option 5: Update: This appears to be the correct solution!
// Class appears on the <td>.
'#wrapper_attributes' => [
'class' => ['option-5-wrapper-attributes'],
],
// Option 6: Has no effect.
'#attributes' => [
'class' => ['option-6-attributes'],
],
// Option 7: Has no effect.
'class' => ['option-7-attributes'],
],
];
