I want to display the row count from the result of the pagination. It works well from the initial page load, however if I add new record, the table component will refresh however the row counter from the @foreach is not changed. How change it?

<?php

namespace AppLivewireUser;

use AppModelsUser;
use LivewireComponent;
use LivewireWithPagination;

class Users extends Component
{
    use WithPagination;

    public $search = "";
    public $sortCol = "id";
    public $sortAsc = false;


    public function sortBy($column)
    {
        if ($this->sortCol == $column) {
            $this->sortAsc = !$this->sortAsc;
        } else {
            $this->sortAsc = true;
        }
        $this->sortCol = $column;
    }

    protected function applySorting($query)
    {
        if ($this->sortCol) {
            $query->orderBy($this->sortCol, $this->sortAsc ? 'asc' : 'desc');
        }
        return $query;
    }

    protected function applySearch($query)
    {
        if ($this->search) {
            $query->where('name', 'like', '%' . $this->search . '%')
                ->orWhere('email', 'like', '%' . $this->search . '%');
        }
        return $query;
    }


    public function updatingSearch()
    {
        $this->resetPage();
    }

    public function render()
    {
        $usersQuery = User::query();
        $this->applySearch($usersQuery);
        $this->applySorting($usersQuery);
        $users = $usersQuery->paginate(10);

        return view('livewire.user.users', ['users' => $users]);
    }
}

            </x-menu.items>
        </x-menu>
    </td>
</tr>

Initally the table looks good. But after adding new records. Here is what happened. Duplicate row number 1.

Keying Livewire components requires :key instead of wire:key as shown in the docs:
```
<livewire:user.user-row :key='{{ $user->id }}' :user="$user" :iteration="$loop->iteration" @user_deleted="$refresh" />
```

Remove the :iteration="$loop->iteration" part from the UserRow component call and adjust the row count display in your parent component’s Blade file.
```
@foreach ($users as $index => $user)
    <livewire:user.user-row wire:key='{{ $user->id }}' :user="$user" 
        :rowNumber="$users->firstItem() + $index" @user_deleted="$refresh" />
@endforeach
```
Add a public property in your UserRow component to accept this value.
```
public $rowNumber;
```
And use the rowNumber property:
```
<tr class="bg-white border-b dark:bg-gray-800 dark:border-gray-700 hover:bg-gray-50 dark:hover:bg-gray-600">
    <td class="px-2 py-2">
        {{ $rowNumber }}
    </td>
</tr>
```
