How to cancel a sorted colum?

Hi, guys!

I'm new to use DataTables. Here is my question.

As i'm using JQuery UI Dialog to popup the datatable to show the data. But i triggered the sort action and closed the dialog, when i opened the dialog again, the DataTables was still being the sorted state! Is there any possible to cancel an already sorted column?

Here is my init code, so i can init datatable without default sort action. But i don't know how to cancel the already sorted state.

$("#table").dataTable({
    "aaSorting" : []
})

Thanks!
