+## View columns
+
+You may render a custom view for a cell using the `view()` method:
+
+```php
+use Filament\Tables\Columns\ViewColumn;
+
+ViewColumn::make('status')->view('filament.tables.columns.status-switcher')
+```
+
+This assumes that you have a `resources/views/filament/tables/columns/status-switcher.blade.php` file.
+
+## Custom classes
+
+You may create your own custom column classes and cell views, which you can reuse across your project, and even release as a plugin to the community.
+
+> If you're just creating a simple custom column to use once, you could instead use a [view column](#view-columns) to render any custom Blade file.
+
+To create a custom column class and view, you may use the following command:
+
+```bash
+php artisan make:table-column StatusSwitcher
+```
+
+This will create the following column class:
+
+```php
+use Filament\Tables\Columns\Column;
+
+class StatusSwitcher extends Column
+{
+    protected string $view = 'filament.tables.columns.status-switcher';
+}
+```
+
+It will also create a view file at `resources/views/filament/tables/columns/status-switcher.blade.php`.
+
+## Accessing the state
+
+Inside your view, you may retrieve the state of the cell using the `$getState()` function:
+
+```blade
+<div>
+    {{ $getState() }}
+</div>
+```
+
+## Accessing the Eloquent record
+
+Inside your view, you may access the Eloquent record using the `$getRecord()` function:
+
+```blade
+<div>
+    {{ $getRecord()->name }}
+</div>
+```
