How to define column type, I need column to be sorted as number

[Er-Kalpesh]

So how to define column type here which is available in normal datatable?

Exp:

$('#example').dataTable({
  "columnDefs": [
    { "type": "num" }
  ]
});

In the same way I need the column to be sorted as a number, so how to define that with yii2?
