Can I add a row with orthogonal data, without using numbers in my data targets?

I've been working with a table that is client-side and I am using data-attributes for order & filter. This all works well.
Then i get some data via ajax, and want to add a row. I can get this to work, but then I am forced into setting all my columnDefs with display, order (which otherwise isn't necessary). This is also ok. What is troublesome to me is that I have to used numbered targets for _ and order. I really like being able to use named targets and not being bound to the order that they are in.

columnDefs: [
{
    targets: ['lname'],
    data: {
        _: '0.display',
        sort: '0.@data-sort' 
    },
 } ... 
]

This is my POC that works: http://jsfiddle.net/97qpagbj/24/
Just want to get rid of the 0. if possible.
