Answer 1

Here is the solution :
[
'attribute' => 'Icon',
'format' => 'html',
'label' => 'Icon',
'value' => function ($data) {
return Html::img(Yii::$app->request->BaseUrl.'/uploads/path/' . $data['Icon'],
['width' => '60px']);
},
],

Answer 2

Check you image path,
You can use
Yii::$app->request->baseUrl
If your index file is on root directory
$url =Yii::$app->request->baseUrl.'/'.$data['image'];

Answer 3

Specify 'format' to 'raw' for image column and $data should be and object, so 'image' field is accessible with $data->image.
[
'attribute'=>'image',
'label'=>'Image',
'format'=>'raw',
'value' => function ($data) {
$url = \Yii::getAlias('#backend/web/').$data->image;
return Html::img($url, ['alt'=>'myImage','width'=>'70','height'=>'50']);
}
],
