Display TextColumn based on model function

What is the best apporach for displaying a TextColumn in my table that references a function on my model? I currently have a Model called Ticket which has a function called remaining() which returns the remaining quantity of the ticket as an integer.

Is that remaining quantity on a related model? Take a look at https://filamentphp.com/docs/3.x/tables/columns/relationships#aggregating-relationships or maybe use accessor (getRemainingAttribute) on the model.

It is not, this is the function on the model: public function remaining(): int { return $this->quantity - $this->bookings()->count(); }

php 

protected $appends = ['remaining'];

public function getRemainingAttribute(): int
{
    return $this->quantity - $this->bookings()->count();
}

php 

protected $appends = ['remaining'];

public function getRemainingAttribute(): int
{
    return $this->quantity - $this->bookings()->count();
}

You cant use sortable or searchable on column @Tim van Heugten correct me if i'm wrong
