+### Column Manager Actions
+
+Filament Tables allows you to customize the placement of the **Reset** and **Apply** actions in the Column Manager. By default:
+
+- The **Reset** action appears in the header.
+- The **Apply** action appears in the footer.
+
+You can change their positions using the corresponding methods.

 #### Displaying the reset action in the footer
 
-By default, the reset action appears in the header of the column manager. You may move it to the footer, next to the apply action, using the `columnManagerResetActionPosition()` method:

+#### Displaying only column groups in the column manager
+

+```php
+use Filament\Tables\Table;
+
+public function table(Table $table): Table
+{
