I might (am) being thick here.

I've added a column called ordr to my DataTable. It is the first column and every row contains a zero, as the rows don't have an initial order in the database:

$('#enq_items').DataTable( {
  columns: [     
    { title: "Order", data: "enqitem.ordr" },

I've also added rowReorder:

$('#enq_items').DataTable( {
  rowReorder: {
    selector: 'tr'
  },

However when I drag a row, the database doesn't update. So I'm guessing I need to tell the database to update the ordr column in the enqitem table. How is this accomplished? Do I need to use the row-reorder event listener?

Also is every row in the table having a zero initially going to cause a problem?

So for example I'd want the DataTable to change this:

ordr | enquiry_number
0    |  10006
0    |  10002
0    |  10018
0    |  10022
0    |  10035

To this:

ordr | enquiry_number
0    |  10018
1    |  10006
2    |  10002
3    |  10022
4    |  10035

Thanks
