order data but disable sorting

Hi, I have a DataTable with several columns (I don't believe the titles or type of data in the column is important). I want to order it by one of the columns, say column 4. When I put in

"order": [ 4, 'desc' ]

It does a wonderful job of putting the data in the column in descending order.

The problem is I also want to disable the user's ability to sort in a different way by clicking on the column title. Right now, if the user clicks on, say, column 1, the table will reorder according to that column's data and will no longer be ordered by column 4's data.

I tried adding the following command:

"ordering": false

I kept in the "order" field to sort by column 4. However, with the "ordering" field on there, the table will no longer sort by column 4, even though I kept that command in the code.

So, how do I sort data by a specific column and also disable the user's ability to sort any other way?

Thanks!
