Is there a way to show a content or content excerpt in a listing table?

[iign]

I have a Post resource and I want to show a preview of the content added with Tiptap. Nothing seems to work. This is the latest code:

return $table
            ->columns(
                [
                    Tables\Columns\TextColumn::make('published_at')->dateTime(),
                    Tables\Columns\TextColumn::make('title'),
                    Tables\Columns\TextColumn::make('content')->formatStateUsing(
                        fn ($state) => $state ? json_decode($state)->document->content[0]->content : ''
                    ),
                    Tables\Columns\TextColumn::make('mood')->formatStateUsing(
                        fn ($state) => match ($state) {
                            1 => '😪',
                            2 => '🫤',
                            3 => '😐',
                            4 => '🙂',
                            5 => '😊',
                        }
                    ),
                ]
            )

In particular, this code throws a Array to string conversion error.

Any help appreciated!

I just do it as an attribute on the model

public function excerpt(): Attribute
{
    $data = $this->content ? tiptap_converter()->asText($this->content) : null;

    return new Attribute(
        get: fn (): ?string => Str::of(strip_tags($data ?? $this->seo->description))->limit(300),
    );
}

That's brilliant, thanks!
