如何在Yii2中使用export kartik下载的文档中添加标题？

"require": {
    "kartik-v/yii2-export": "@dev"
}

use kartik\export\ExportMenu;

echo ExportMenu::widget([
    'dataProvider' => $dataProvider,
    'columns' => $columns,
    'filename' => 'Exported Data',
    'target' => ExportMenu::TARGET_BLANK,
    'showConfirmAlert' => false,
    'showColumnSelector' => false,
    'dropdownOptions' => [
        'label' => 'Export',
        'class' => 'btn btn-default',
    ],
    'exportConfig' => [
        ExportMenu::FORMAT_HTML => false,
        ExportMenu::FORMAT_CSV => false,
        ExportMenu::FORMAT_TEXT => false,
        ExportMenu::FORMAT_PDF => [
            'pdfConfig' => [
                'methods' => [
                    'SetTitle' => 'Your Title Here', // 设置标题
                    'SetSubject' => 'Your Subject Here',
                    'SetHeader' => ['Your Header Here'],
                    'SetFooter' => ['Your Footer Here'],
                ],
            ],
        ],
    ],
]);
