How to color rows depending on data values Yii CGridView

Question

I have Users model.

Displaying it with CGridView i want to color the rows depending on $model->is_admin which is an integer either 0 or 1, so either of 2 colors.

Could it be done by simple settings of CGridView ?

Controller

/**
* Lists all models.
*/
public function actionIndex() {
    $model = new Users('search');
    $model->unsetAttributes();  // clear any default values
    if (isset($_GET['Users']))
        $model->attributes = $_GET['Users'];

    $this->render('index', array(
        'model' => $model,
    ));
}

View

<div class="row">
    <div class="col-sm-12 table-responsive">
        <?php
        $this->widget('zii.widgets.grid.CGridView', array(
            'id' => 'users-grid',
            'itemsCssClass' => 'table table-bordered table-hover dataTable',
            'dataProvider' => $model->search(),
            'enablePagination' => false,
            // 'filter'=>$model,
            'columns' => array(
                'username',
                'first_name',
                'last_name',
                'email',
                ),
                array(
                    'class' => 'CButtonColumn',
                ),
            ),
        ));
        ?>
    </div>
</div>

Here is a good looking example which may help you:

http://www.yiiframework.com/wiki/314/cgridview-use-special-variable-data-in-the-htmloptions-of-a-column-i-e-evaluate-htmloptions-attribute/

I had no luck implementing it by myself, using only build-in features, so it might be the only option. I did not try this one, but as comments say, it should work.

EDIT: I made it, much shorter way

$this->widget('zii.widgets.grid.CGridView', array(
    'dataProvider' => $data_provider,
    'rowCssClassExpression' => '$data["is_admin"] ? "tr_isadmin" : ""',
    'columns' => array(
        array(
            'header' => 'Is admin?',
            'name' => 'is_admin',
        ),
    ),
);

So, rowCssClassExpression adds a class for tr wrapper based on $data["is_admin"] value.

Then, simply add css like

.tr_isadmin { 
    background-color: red; 
}

Of course, it is just simplified example. You have to adapt it for your purpose.
