Is it possible to use n or in Yii2 Kartik GridView DataColumn title?

I have a table with many colomns. It has a big lable strings and smal data strings, like ‘Average usage time’ and ’55’,

| Average usage time |
______________________
|                  55|

so i want to show label in a few lines, like

| Average|
|   usage|
|    time|
| _______|
|     55 |

to fit table into screen. Problem is that DataColumn ignore both ‘n’ symbol and br tags in label. Is there any way to do this?

DataColumn example:

[
'attribute' => 'avg_usage_time',
'label' => 'Average <br>usage time',
'vAlign'=>'middle',
'content' => function($model) {
    return number_format($model['avg_usage_time'], 0, '.', ' ');
    },
'pageSummary' => function ($summary, $data, $widget) {
    return (isset($summary) && is_numeric($summary)) ? number_format($summary, 0, '.', ' ') : 0;
    },
 ],

Answer

Here is your solution please add type attribute.

[
'attribute' => 'avg_usage_time',
'label' => 'Average <br>usage time',
'type' => 'raw'
'vAlign'=>'middle',
'content' => function($model) {
    return number_format($model['avg_usage_time'], 0, '.', ' ');
    },
'pageSummary' => function ($summary, $data, $widget) {
    return (isset($summary) && is_numeric($summary)) ? number_format($summary, 0, '.', ' ') : 0;
    },
 ],

may it helps you. please add this 'type' => 'raw' in attribute it allows to use html.
