+If the route parameters cannot be determined automatically based on the entity, user-defined routes can be created by overwriting `data`. Once `data` is overwritten, `routeName` and `routeParams` are no longer necessary to specify.

+```php
+use HelloSebastian\HelloBootstrapTableBundle\Columns\LinkColumn;
+
+->add('department.name', LinkColumn::class, array(
+    'title' => 'Department',
+    'data' => function (User $user) {
