Not shown datatable in Laravel

For some reason, the data in the table does not appear using DataTables. And if I remove the return view ('home'), I get a query that eats the whole page

The home view:

    <link href="https://cdn.datatables.net/1.10.16/css/jquery.dataTables.min.css" rel="stylesheet">
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.js"></script>

}

The routes in web.php

Route::get('/', function () {
return view('welcome');
});


Auth::routes();

Route::get('/home', 'HomeController@index')->name('home');
Route::post('/home/sendData', 'HomeController@sendData')->name('home/sendData');

Route::get('/home/create', 'HomeController@create');
Route::get('/home/index', 'HomeController@index');

What I have in the Product Provider

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Product extends Model
 {
 protected $fillable = ['nombre', 'precio', 'empresa'];
}

This is my database, I want you to get the product data

CREATE TABLE 'products' (
'id' int(10) UNSIGNED NOT NULL,
'producto' varchar(191) COLLATE utf8mb4_unicode_ci NOT NULL,
'precio' varchar(191) COLLATE utf8mb4_unicode_ci NOT NULL,
'empresa' varchar(191) COLLATE utf8mb4_unicode_ci NOT NULL,
'created_at' timestamp NULL DEFAULT NULL,
'updated_at' timestamp NULL DEFAULT NULL) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
