-To hide a summary conditionally, you may use the `hidden()` method:
+To hide a summary, you may pass a boolean, or a function that returns a boolean, to the `hidden()` method. If you need it, you can access the Eloquent query builder instance for that summarizer via the `$query` argument of the function:
 
 ```php
 use Filament\Tables\Columns\Summarizers\Summarizer;
 use Filament\Tables\Columns\TextColumn;
 use Illuminate\Database\Eloquent\Builder;
 
-TextColumn::make('name')
+TextColumn::make('sku')
     ->summarize(Summarizer::make()

+        ->hidden(fn (Builder $query): bool => ! $query->exists()))
