problems with "yii2 export" to export to csv

I try to use from kartik-v: yii2-export (with the module grid) (grid from kartik-v:

Did not get to do the export setting (put delimiter, create your own name for the file);

On site:

written default settings:

"The default exportConfig is setup as below".

For their changes I write settings in a property: exportConfig in GridView.

No results are not present, the file is exported with the default settings. And the property itself "exportConfig" successfully parsed like widget GridView, by parseExportConfig.

Since I am suffering for about a day with this, I decided to tweak these settings, the "default", but it does not give (. Settings loaded unclear from where ((

use yii\helpers\Html;

use kartik\grid\GridView;

use kartik\export\ExportMenu;

$gridColumns = [

        ['class' => 'yii\grid\SerialColumn'],




        ['class' => 'yii\grid\ActionColumn'],



    // Renders a export dropdown menu

    echo ExportMenu::widget([

        'dataProvider' => $dataProvider,

        'columns' => $gridColumns



        'dataProvider' => $dataProvider,

        'filterModel' => $searchModel,

        'columns' => $gridColumns,
