kartik的yii2-网格:设置未知属性: kartik\grid\GridView::panel

Question

对于我来说，在使用Kartik的yii2-网格时，我无法对以下错误进行排序：

设置未知属性:kartik\grid\GridView：：面板

我的代码是：

use yii\helpers\Html;
use kartik\grid\GridView;

[...]

    <?= GridView::widget([
        'dataProvider' => $dataProvider,
        'filterModel' => $searchModel,
        'hover' => true,
        'persistResize' => true,
        'pager' => [
             'firstPageLabel' => Yii::t('app', 'Inicio'),
             'lastPageLabel' => Yii::t('app', 'Final'),
             'maxButtonCount' => Yii::$app->params['numBotones'],
          ],
        'panel ' => [
            'heading'=>'<h1>'.Html::encode(mb_strtoupper($this->title)).'</h1>', 
        ],
        'columns' => [
             ['class' => 'kartik\grid\SerialColumn'],

            [...]

然而，hover和persistResize确实有效。

我的composer.json还包含：

​

    "minimum-stability": "stable",
    "require": {
        "php": ">=5.4.0",
        "yiisoft/yii2": "*",

    },

有什么想法吗？

似乎您在属性'panel '中有一个空白

 'panel ' => [
        'heading'=>'<h1>'.Html::encode(mb_strtoupper($this->title)).'</h1>', 
    ],

试着把它移开

   'panel' => [
        'heading'=>'<h1>'.Html::encode(mb_strtoupper($this->title)).'</h1>', 
    ],
