Laravel excel export problem

I have more than one table. How can i only using one model and controller to export the different tables contents? Route :

Route::get('export',function() { return view('export'); }); Route::get('exportTo/{type}', 'ExportController@index');

Model :

namespace App; use Illuminate\Database\Eloquent\Model;

class TestModel extends Model { protected $table = 'posts'; protected $fillable = ['title', 'content']; }

Controller

namespace App\Http\Controllers;

use Illuminate\Http\Request; use Illuminate\Support\ServiceProvider; use App\Http\Requests; use App\Http\Controllers\Controller; use Excel; use App\AccessModel;

class ExportController extends Controller { public function index($type) {

>$data = AccessModel::get(['customer_name', 'company_name'])->toArray(); return Excel::create('Accesses Record', function ($excel) use ($data) { $excel->sheet('mySheet', function ($sheet) use ($data) { $sheet->fromArray($data); }); })->download($type);

Views:

          ` <div class="btn-group">
                        <a href="{{ url('exportTo/xls') }}">
                            <button class="btn btn-primary"><span class="glyphicon glyphicon-export"></span> Export
                                to xls
                            </button>
                        </a>
                        <a href="{{ url('exportTo/xlsx') }}">
                            <button class="btn btn-info"><span class="glyphicon glyphicon-export"></span> Export to
                                xlsx
                            </button>
                        </a>
                        <a href="{{ url('exportTo/csv') }}">
                            <button class="btn btn-warning"><span class="glyphicon glyphicon-export"></span> Export
                                to CSV
                            </button>
                        </a>
                    </div>`
