     - `heading_permalink/apply_id_to_heading` - When `true`, the `id` attribute will be applied to the heading element itself instead of the `<a>` tag
     - `heading_permalink/heading_class` - class to apply to the heading element
     - `heading_permalink/insert` - now accepts `none` to prevent the creation of the `<a>` link

+### Alignment
+
+You can configure the HTML attributes used for alignment via the `alignment_attributes` option. For example, if you wanted Bootstrap classes to be applied, you could do so like this:
+
+```php
+$config = [
+    'table' => [
+        'alignment_attributes' => [
+            'left' => ['class' => 'text-start'],
+            'center' => ['class' => 'text-center'],
+            'right' => ['class' => 'text-end'],
+        ],
+    ],
+];
+```
+
+Or you could use inline styles:
+
+```php
+$config = [
+    'table' => [
+        'alignment_attributes' => [
+            'left' => ['style' => 'text-align:left'],
+            'center' => ['style' => 'text-align:center'],
+            'right' => ['style' => 'text-align:right'],
+        ],
+    ],
+];
+```
+
+Or any other HTML attributes you'd like!

 The Table functionality was originally built by [Martin Hasoň](https://github.com/hason) and [Webuni s.r.o.](https://www.webuni.cz) before it was merged into the core parser.
