Filament also offers convenient ways to group table data by columns and calculate the aggregated data like "sum" or "average" to show at the bottom.

To demonstrate that, I've created a new Model for Orders:

php artisan make:model Order -m

Migration:

Schema::create('orders', function (Blueprint $table) {
    $table->id();
    $table->foreignId('user_id')->constrained();
    $table->foreignId('product_id')->constrained();
    $table->integer('price');
    $table->timestamps();
});

app/Models/Order.php:

class Order extends Model
{
    protected $fillable = ['user_id', 'product_id', 'price'];
 
    public function user(): BelongsTo
    {
        return $this->belongsTo(User::class);
    }
 
    public function product(): BelongsTo
    {
        return $this->belongsTo(Product::class);
    }
}

And added some data for the orders:

Then, we can generate a new Filament Resource to show the table of Orders:

php artisan make:filament-resource Order

The table has these values:

app/Filament/Resources/OrderResource.php:

class OrderResource extends Resource
{
    // ...
 
    public static function table(Table $table): Table
    {
        return $table
            ->columns([
                Tables\Columns\TextColumn::make('created_at')
                    ->dateTime(),
                Tables\Columns\TextColumn::make('product.name'),
                Tables\Columns\TextColumn::make('user.name'),
                Tables\Columns\TextColumn::make('price')
                    ->money('usd')
                    ->getStateUsing(function (Order $record): float {
                        return $record->price / 100;
                    })
            ])
            ->defaultSort('created_at', 'desc')
            // ... other methods with default values
    }
}

Here's how it looks now:

Grouping by Product Name

What if you want to divide this table by some condition? Let's try to group by product. Then, you just...
