Would like to use child rows. How do I initialize the child rows?

daveri

Fairly new at this. I've studied the example for child rows.
I don't understand the example javascript lines 1-18:

/* Formatting function for row details - modify as you need */
function format ( d ) {
// d is the original data object for the row
return '

'+ ''+ ''+ ''+ ''+ ''+ ''+ ''+ ''+ ''+ ''+ ''+ ''+ '

Full name:	'+d.name+'
Extension number:	'+d.extn+'
Extra info:	And any further details here (images etc)...

';
}

What do I replace //'d' . . . . with?
My table is defined:
$(document).ready(function() {
var table = $('#example').dataTable( {
"ajax": "jwreck.json",
"columns": [
{
"class": 'details-control',
"orderable": false,
"data": null,
"defaultContent": ''
},

        { "data": "vname" },
        { "data": "vtype" },
        { "data": "losscause" },
        { "data": "losstype" },
        { "data": "ylost", text_data_delimiter: ",", filter_type: "auto_complete" },
        { "data": "homeport" }
        ],
    "order": [[1, 'asc']]
      });

Can you provide an example with the full code?

Thank you,
