Answer 1

Everytime I have had that problem with dataTables it stems from a javascript error.
Also, you could try adding

"bSort": true,

Answer 2

I just UPGRADED JQuery datatable, now works fine

Answer 3

I had the problem too. Just use their own configurator to setup all the options you want form here https://datatables.net/download/ they will generate exactly the .js and .css files you need. You then can either download or use their own hosted CDN for both files

If you are using BundleConfig, please add the following reference:
