Introduction

You may create your own custom column classes and views, which you can reuse across your project, and even release as a plugin to the community. To create a custom column class and view, you may use the following command: 
php artisan make:filament-table-column AudioPlayerColumn
This will create the following component class: 
use Filament\Tables\Columns\Column;

class AudioPlayerColumn extends Column
{
    protected string $view = 'filament.tables.columns.audio-player-column';
}
It will also create a view file at resources/views/filament/tables/columns/audio-player-column.blade.php.
Filament table columns are not Livewire components. Defining public properties and methods on a table column class will not make them accessible in the Blade view.

​
Accessing the state of the column in the Blade view

Inside the Blade view, you may access the state of the column using the $getState() function: 
<div>
    {{ $getState() }}

​
Accessing the Eloquent record in the Blade view

Inside the Blade view, you may access the current table row’s Eloquent record using the $record variable: 
<div>
    {{ $record->name }}

​
Accessing the current Livewire component instance in the Blade view

Inside the Blade view, you may access the current Livewire component instance using $this: 
@php
    use Filament\Resources\Users\RelationManagers\ConferencesRelationManager;
@endphp

<div>
    @if ($this instanceof ConferencesRelationManager)
        You are editing the conferences of a user.
    @endif

​
Accessing the current column instance in the Blade view

Inside the Blade view, you may access the current column instance using $column. You can call public methods on this object to access other information that may not be available in variables: 
<div>
    @if ($column->isLabelHidden())
        This is a new conference.
    @endif

​
Adding a configuration method to a custom column class

You may add a public method to the custom column class that accepts a configuration value, stores it in a protected property, and returns it again from another public method: 
use Filament\Tables\Columns\Column;

class AudioPlayerColumn extends Column
{
    protected string $view = 'filament.tables.columns.audio-player-column';
    
    protected ?float $speed = null;

    public function speed(?float $speed): static
    {
        $this->speed = $speed;

        return $this;
    }

    public function getSpeed(): ?float
    {
        return $this->speed;
    }
}
Now, in the Blade view for the custom column, you may access the speed using the $getSpeed() function: 
<div>
    {{ $getSpeed() }}
Any public method that you define on the custom column class can be accessed in the Blade view as a variable function in this way. To pass the configuration value to the custom column class, you may use the public method: 
use App\Filament\Tables\Columns\AudioPlayerColumn;

AudioPlayerColumn::make('recording')
    ->speed(0.5)

​
Allowing utility injection in a custom column configuration method

Utility injection is a powerful feature of Filament that allows users to configure a component using functions that can access various utilities. You can allow utility injection by ensuring that the parameter type and property type of the configuration allows the user to pass a Closure. In the getter method, you should pass the configuration value to the $this->evaluate() method, which will inject utilities into the user’s function if they pass one, or return the value if it is static: 
use Closure;
use Filament\Tables\Columns\Column;

class AudioPlayerColumn extends Column
{
    protected string $view = 'filament.tables.columns.audio-player-column';
    
    protected float | Closure | null $speed = null;

    public function speed(float | Closure | null $speed): static
    {
        $this->speed = $speed;

        return $this;
    }

    public function getSpeed(): ?float
    {
        return $this->evaluate($this->speed);
    }
}
Now, you can pass a static value or a function to the speed() method, and inject any utility as a parameter: 
use App\Filament\Tables\Columns\AudioPlayerColumn;

AudioPlayerColumn::make('recording')
    ->speed(fn (Conference $record): float => $record->isGlobal() ? 1 : 0.5)
