JSON data - Require 'aaData' not 'aoColumns'

I've a JSON object which I would like to show as a table using DataEditors. Found

aaData

and

aoColumns

for it. A condition where I struck was, is it okay even If I don't specify the

aoColumns

attribute information? I have got some formatting conditions to be done on my header. Bottom line is, I'd like to render data (tbody) without touching header (th)?
