Table row colorization

Please, this isn't working, am I doing anything wrong.

->recordClasses(fn (Model $record) => $record->low_quantity < $record->quantity_available ? 'bg-red-600 text-white' : '')

->recordClasses(fn (Model $record) => $record->low_quantity < $record->quantity_available ? 'bg-red-600 text-white' : '')
