    </div>
</div>
<?php
$this->registerJs("

    $('td').click(function (e) {
        var id = $(this).closest('tr').data('id');
        if(e.target == this)
            location.href = '" . Url::to(['site/subcategory']) . "?id=' + id;
    });

");?

Controller function

public function actionSubcategory($id)
    {
        
        $category = new Category();
        $category->getCategorybyid($id);
        $Subcategory = new Subcategory();
        $dataProvider = new ActiveDataProvider([
            'query' => $Subcategory->getSubcategory(),
            'pagination' => [
                'pageSize' => 20,
            ],
        ]);
        return $this->render('subcategory', [
            'dataProvider' => $dataProvider]);

    }
