How to pass column with variable to a component’s slot in Laravel blade?

Im using to Laravel blade’s component to make a dynamic table, in which user can pass in header, and corresponding rows. I wanna use this component to display many tables (permissions, reviews, etc…). I use it in my view like this

                <x-admin.data-table :items="$review" route="admin/users">
                    <x-slot:header>
                        <th>Name</th>
                        <th>Description</th>
                    </x-slot>
                    <x-slot:row :item="$item">
                        <td>{{$item->name}}</td>
                        <td>{{$item->description}}</td>
                    </x-slot:row>
                </x-admin.data-table>

The row slot is display in data-table.blade.php like this

<tbody>
@foreach ($items as $item)
   <tr>
      {{ $row(['item' => $item]) }}
   </tr>
@endforeach
</tbody>

This part

                    <x-slot:row :item="$item">
                        <td>{{$item->name}}</td>
                        <td>{{$item->description}}</td>
                    </x-slot:row>

this is where people want to reuse this component, can pass their own attribute, i.e <td>{{$item->content}}</td>.
But what i get is Undefined variable $item. I tried using {{ $row->with(['item' => $item]) }} too, but still a no. How should I pass the columns to my slot then?
