You are currently viewing the documentation for Filament 3.x, which is a previous version of Filament.
Looking for the current stable version? Visit the [5.x documentation](/docs/5.x/tables/columns).
## Table column utility injection
The vast majority of methods used to configure columns accept functions as parameters instead of hardcoded values:
```php theme={"theme":"gruvbox-dark-hard"}
use Filament\Tables\Columns\TextColumn;
TextColumn::make('status')
->color(fn (string $state): string => match ($state) {
'draft' => 'gray',
'reviewing' => 'warning',
'published' => 'success',
'rejected' => 'danger',
})
```
This alone unlocks many customization possibilities.
The package is also able to inject many utilities to use inside these functions, as parameters. All customization methods that accept functions as arguments can inject utilities.
These injected utilities require specific parameter names to be used. Otherwise, Filament doesn't know what to inject.
### Injecting the current state of a column
If you wish to access the current state (value) of the column, define a `$state` parameter:
```php theme={"theme":"gruvbox-dark-hard"}
function ($state) {
// ...
}
```
### Injecting the current Eloquent record
If you wish to access the current Eloquent record of the column, define a `$record` parameter:
```php theme={"theme":"gruvbox-dark-hard"}
use Illuminate\Database\Eloquent\Model;
function (Model $record) {
// ...
}
```
Be aware that this parameter will be `null` if the column is not bound to an Eloquent record. For instance, the `label()` method of a column will not have access to the record, as the label is not related to any table row.
### Injecting the current column instance
If you wish to access the current column instance, define a `$column` parameter:
```php theme={"theme":"gruvbox-dark-hard"}
use Filament\Tables\Columns\Column;
function (Column $column) {
// ...
}
```
### Injecting the current Livewire component instance
If you wish to access the current Livewire component instance that the table belongs to, define a `$livewire` parameter:
```php theme={"theme":"gruvbox-dark-hard"}
use Filament\Tables\Contracts\HasTable;
function (HasTable $livewire) {
// ...
}
```
### Injecting the current table instance
If you wish to access the current table configuration instance that the column belongs to, define a `$table` parameter:
```php theme={"theme":"gruvbox-dark-hard"}
use Filament\Tables\Table;
function (Table $table) {
// ...
}
```
### Injecting the current table row loop
If you wish to access the current [Laravel Blade loop object](https://laravel.com/docs/blade#the-loop-variable) that the column is rendered part of, define a `$rowLoop` parameter:
```php theme={"theme":"gruvbox-dark-hard"}
function (stdClass $rowLoop) {
// ...
}
```
As `$rowLoop` is [Laravel Blade's `$loop` object](https://laravel.com/docs/blade#the-loop-variable), you can access the current row index using `$rowLoop->index`. Similar to `$record`, this parameter will be `null` if the column is currently being rendered outside a table row.
### Injecting multiple utilities
The parameters are injected dynamically using reflection, so you are able to combine multiple parameters in any order:
```php theme={"theme":"gruvbox-dark-hard"}
use Filament\Tables\Contracts\HasTable;
use Illuminate\Database\Eloquent\Model;
function (HasTable $livewire, Model $record) {
// ...
}
```
### Injecting dependencies from Laravel's container
You may inject anything from Laravel's container like normal, alongside utilities:
```php theme={"theme":"gruvbox-dark-hard"}
use Illuminate\Database\Eloquent\Model;
use Illuminate\Http\Request;
function (Request $request, Model $record) {
// ...
}
```
)}
