Laravel DataTable - $dataTable未定义

Question

我创建了一个模型、控制器、工厂和dataTable文件，但laravel一直向我显示错误$dataTable is undefined

怎么会这样?是路由问题还是我没有正确地将控制器连接到刀片上？

我的控制器：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\DataTables\DataEntry\ReportsDataTable;

class ReportsController extends Controller
{
    public function index(ReportsDataTable $dataTable)
    {
        return $dataTable->render("pages.dataEntry.reports.index");
    }
}

的路线：

// Data Entry pages
    Route::prefix('dataEntry')->name('dataEntry.')->group(function () {
        Route::resource('reports', ReportsController::class)->only(['index']);
    });

index.blade:

<x-base-layout>

    <!--begin::Card-->
    <div class="card">
        <!--begin::Card body-->
        <div class="card-body pt-6">
            <!--begin::Table-->
             {{ $dataTable->table() }}
            <!--end::Table-->

            {{-- Inject Scripts --}}
             {{ $dataTable->scripts() }}
        </div>
        <!--end::Card body-->
    </div>
    <!--end::Card-->

</x-base-layout>

public function index()
{
    return ReportsDataTable::all()->render("pages.dataEntry.reports.index");
}
