Data Table Error :: Cannot read property ‘fnSetData’ of undefined

Initial code looks like this..

var oTable = $('#sim_data').dataTable( {
    aoColumns: [ {"sName": "ss" },{"sName": "sim_no"}, {"sName": "sale_price"}, {"sName":   "purchased_price"},{"sName": "status"} ]



Only when I try to initialize aoColumns as above returns error

Cannot read property 'fnSetData' of undefined

and with out this initialization it works

I had the same problem today. Make sure the number of elements in your “aoColumns” matches the number of columns you actually have in your table.

In my case, that was the problem.
