unable to fix grid view row height in yii2

Question

I need to fix row height in a grid view, where some table rows may include big text. I have tried a lot of what I have searched. Sometimes my footer overlaps my table, this is also a factor to be taken into consideration (when I tried to fix the table height. Thanks in advance, and this is my code:

     <?php

use app\models\SearchAppEvent;
use yii\data\ActiveDataProvider;
use yii\grid\GridView;
use yii\helpers\Html;
use yii\web\View;

    /* @var $this yii\web\View */
    /* @var $searchModel app\models\SearchAppEvent */
    /* @var $dataProvider yii\data\ActiveDataProvider */

    $this->title = Yii::t('event', 'App Event');
    $this->params['breadcrumbs'][] = $this->title;
    ?>
    <style>
        /*    tr {
                height: 100px;
                text-overflow: ellipsis;
            }
            td {
                height: 50px;
                text-overflow: ellipsis;        
            }
                .myclass{
                    height: 50px;
                    text-overflow: ellipsis;
                }
            .mydiv tr {
                height: 50px;
                text-overflow: ellipsis;                
            }
            .mydiv td {
                height: 50px;
                text-overflow: ellipsis;                
            }*/
    </style>
    <div class="app-event-index">

        <h1><?= Html::encode($this->title) ?></h1>

Answer 1

I have added a function that removes overflow from the text, and keeps the first 200 chars for example. It is not the optimal solution, but I have finished the website.
