Expose Laravel Loop Object To Column

[Nuhel]

Sometime we need to show the Serial Number/Iteration Number in table. I could not find any way to do this with filament table. (May be there is a way, if so i will close this PR)

This PR Expose Laravel Loop Object To Columns,

We can use it like below

Tables\Columns\TextColumn::make('sl')->getStateUsing(function ($loop){
      return $loop->iteration;
}),

Also as it is laravel's foreach loop object, We can access every other property like
index, remaining, count etc.

[what-the-diff]

• Added rowIndex() method to TextColumn
• Added HasRowLoopObject trait and $loop property in Column class
• Passed $rowLoop object from index view component to layout components

Instead of loop, please use rowIndex and start from 0

You mean instead of loop object just pass an int that starts from 0?

[danharrin]

well at the moment you're passing in the column loop object and not the row loop object? i think? which is wrong right?

Yes, if we pass the loop object, we will have some extra options like remaining, count, depth, last etc, which will help if we need those.

But it's your call , i will update the PR if you think loop object is not a good fit.

I agree now that the loop object is fine, but please test your code. I don't think it works, as you're passing in the column loop and not the row loop. For clarity we can name it rowLoop() as well, but I think it still needs fixing

Yes I was passing column loop -_- .

Test With normal Table Layout.

Test with Split and Stack

I've just refactored a bit, does it still work?

Not Working With Stack & Split.
Filament\Tables\Columns\Column::rowLoop(): Argument #1 ($loop) must be of type ?stdClass, Closure given,

{{ $layoutComponent->viewData(['recordKey' => $recordKey, 'rowLoop' => $rowLoop]) }}

rowLoop has to be passed in viewData.

@Nuhel how about passing it into the object instead and then using $getRowLoop() in the view? I've added the trait to the Component object

May be i did not get you, can you elaborate please?

[danharrin]

I've made the changes, test again please

Yes working.

Should I update documentation? And I am thinking to add below function to CanFormatState Trait

public function rowIndex(bool $fromZero = false): static
{
    $this->getStateUsing(static function ($rowLoop) use($fromZero): ?string {
        return $rowLoop->{ $fromZero? "index":"iteration"};
    });

    return $this;
}
