How to specify class for specific td in Yii2 GridView?

Question

Yii

There was a task to add a class to a certain td in the tables

'columns' => [
        [
            'attribute' => 'user',
            'format' => 'html',
            'label'  => Yii::t('articles.main', 'Автор'),
            'value' => function ($model) {
                return UserColumn::widget([
                    'userId' => $model->user_id
                ]);
            }
        ],
        [
            'attribute' => 'text',
            'format' => 'html',
            'value' => function ($model) {
                return '<div class="text-left">' . $model->text .  '</div>';
            }
        ],
      ...

Generates:

...
<td> ... </td>
<td> ... </td>
...

Is it possible somehow only for the user attribute to add the test class, for example, I tried something like this:

'columns' => [
        [
            'attribute' => 'user',
            'format' => 'html',
            'options' => ['class'=>'test'],
            'label'  => Yii::t('articles.main', 'Автор'),
            'value' => function ($model) {
                return UserColumn::widget([
                    'userId' => $model->user_id
                ]);
            }
        ],

but something is not right.

Answer 1

/**
     * @var array|\Closure the HTML attributes for the data cell tag. This can either be an array of
     * attributes or an anonymous function that () that returns such an array.
     * The signature of the function should be the following: `function ($model, $key, $index, $gridView)`.
     * A function may be used to assign different attributes to different rows based on the data in that row.
     *
     * @see \yii\helpers\Html::renderTagAttributes() for details on how attributes are being rendered.

    public $contentOptions = [];

Many programmers will probably hate me now, but I'm tired of hearing that
GridView is bad and not flexible. Well, firstly, it inherits from other widgets, and if you are not too lazy, you can find several, and so, my code example is not ideal, only as one of the types of solution, so that you understand what can be squeezed out of it.
We write a function to the model News():

...
<?php 
    public function sklonen($n,$s1,$s2,$s3, $b = false){
        $m = $n % 10; $j = $n % 100;
        if($b) {$n = '<b>'.$n.'</b>';}
        if($m==0 || $m>=5 || ($j>=10 && $j<=20)) {return $n.' '.$s3;}
        if($m>=2 && $m<=4) {return  $n.' '.$s2;}
        return $n.' '.$s1;
    }
...

In controller:

...
    public function actionNews()
    {
        $searchModel = new NewsSearch();
        $dataProvider = $searchModel->search(Yii::$app->request->queryParams); // ищешь через LIKE
        return $this->render('news', [
            'searchModel' => $searchModel,
            'dataProvider' => $dataProvider,            
        ]);
    }
...

In model NewsSearch():

...
$dataProvider = new ActiveDataProvider([
    'query' => News::find()->where(['visibility'=>1])->orderBy('date DESC'),
    'pagination' => [
        'pageSize' => 20, // говоришь системе мне нужно вывести 20 записей
    ],
]);
...

Now in view:

<?php
    use yii\helpers\Html;
    use yii\widgets\Pjax;
    use yii\grid\GridView;
    use budyaga_cust\users\models\News;
    $this->title = 'Новости';
    $this->params['breadcrumbs'][] = $this->title;
?>
<?php Pjax::begin(); ?> 
<?= GridView::widget([
    'dataProvider' => $dataProvider,
    //'filterModel' => $searchModel,
    'showHeader' => false, // вырезаем шапку таблицы
    'tableOptions' => [
        'class' => 'table' // можно задать свой, тут 100% ширина блока
    ], 
    'options' => ['tag' => 'div', 'class' => 'col-lg-12'], // оборачиваем в div с Bootstrap CSS
    'emptyTextOptions' => ['tag' => 'p', 'class' => 'text-center text-danger'],
    'emptyText' => 'По вашему запросу ничего не найдено',
    'summary' => '<br/><p class="text-center text-muted">Всего найдено '.News::sklonen( '{totalCount}', 'новость', 'новости', 'новостей').'</p>', // 127
    'layout' => '{summary}{items}',  // настраиваем внешний вид как нам надо
        'columns' => [
            //['class' => 'yii\grid\SerialColumn'], // нумерация строк может вообще не пригодится
            [
                // 'attribute' => 'img', // если много атрибутов в контенте можно это не писать
                'format' => 'raw',
                'label' => '',
                'content'=>function($data){
                    return '
                            <div class="row">
                                <div class="col-md-3">
                                    '.Html::a(Html::img('/img/box/'.$data->img,
                                            [
                                                'class' => 'thumbnail', 
                                                'alt' => $data->header, 
                                                'style' => 'width:100%;'
                                            ])
                                    ,'/new/'.$data->link).'                                
                                </div>
                                <div class="col-md-9 products">
                                '.Html::a($data->header, '/new/'.$data->link).'
                                '.Html::tag('p', $data->text).'
                                '.Html::a('подробнее', '#',['class' =>'buttons pull-right']).'
                                </div>
                            </div>
                        ';
                }
            ],
        ], // может понадобится по дизайну, чтобы пагинация была в другом месте
    ]); ?>
<?= GridView::widget([
    'dataProvider' => $dataProvider,  
    'showHeader' => false,
    'showOnEmpty' => false,
    'summary' => 'страницы {page} из {pageCount}',
    'layout' => '<div class="page-nav td-pb-padding-side">{pager}<span class="pages">{summary}</span></div>', // формируем внешний вид пагинации
    'pager' => [
        'maxButtonCount' => 5, // максимум 5 кнопок
        'options' => ['id' => 'mypager', 'class' => 'pagination'], // прикручиваем свой id чтобы создать собственный дизайн не касаясь основного.
        'nextPageLabel' => '<i class="ionicons ion-arrow-right-c"></i>', // стрелочка в право
        'prevPageLabel' => '<i class="ionicons ion-arrow-left-c"></i>', // стрелочка влево
    ],  
]); ?> 
<?php Pjax::end(); ?>

ALL ! Here is the working code, customize to your liking, there may be criticism, but! This code is responsive! That is, you can make a search for goods and services out of this, and for any content, and it will be flexible for all devices, plus ajax will make it incredibly fast and easy, like you click on tabs. I took the inherited widgets out of the box, did not invent anything, I collected the material from the documentation.

Thank you all for your attention. Till! )))

I'm not strong in yii2, but this is how it works

GridView::widget([
       // ...
       // --------------------- КЛАСС ДЛЯ строки -------------------------------
        'rowOptions'=>function ($model, $key, $index, $grid){
            $class=($model->confirmed)?'confirmed-row':'';
            return [
                'key'=>$key,
                'index'=>$index,
                'class'=>$class
            ];
        },
       
        'columns'      => [
            [
                'attribute' => 'confirmed',
                // ----------------------  КЛАСС ДЛЯ СТОЛБЦА -----------------------
                'contentOptions' => ['class' => 'text-center'],
                'value' => function ($model) {
                   // ...
                },
                'format' => 'html',
           
            ],
            
        ],
    ]);
