Disable Sorting Icon Issue

prem2

Hi,

I am trying to hide the sorting functionality for particular columns. I succeed with below coding. But, there is an issue of hiding the arrow icon for column index-0.

Here is the live demo,

Source Code
"columnDefs": [ { "orderable": false, "targets": [0,1] } ]

Kindly, provide your suggestion.

Thanks,
Prem
