Javascript Question

jquery datatable sorts columns even when orderable false specified in columndefs

Im facing a strange problem with JQUERY Datatable plugin. I've a rating feature being used in every rows. The first cell actually holds the control for that purpose.

Here is the markup for the first cell

<input class="row-check" type="checkbox"><span class="fa-stack fa-lg star-rating">
<i class="fa fa-star goldstar fa-stack-2x"></i>
<strong class="fa-stack-1x inside-text">4</strong> </span>


Here is the Datatable initialization code Im using

var myTable = $("#tbl_main").dataTable({
"dom": "<'tableinfobar'i><'tablesearchbox'f><'tablestarfilter'><'tablestarreset'><'tablebody't>S<'tablelength'l><'tablepaging'p>",
"ordering": true,
"columnDefs": [{ "targets": [0, 6], "searchable": false, "orderable": false },
{ "targets": [ 1, 3, 4, 5, 7, 8, 9], "orderable": false },
{ "targets": [2], "type": "html-num", "orderable": true}],
"lengthMenu": [
[10, 20, 50, 100, 500, -1],
[10, 20, 50, 100, 500, "All"]
],
"language": {
"search": "Quick Search _INPUT_",
"zeroRecords": "No assessments found with that search criteria.",
"info": "Showing _START_ to _END_ of _TOTAL_ Assessments",
"infoFiltered": " - filtered from _MAX_ entries",
"lengthMenu": "Show _MENU_ Entries"
}
}).show();


As you can see in the code, I disabled sorting for the first column in the columndefs. But still if some values inside the first cells Strong tags (In this case
<strong class="fa-stack-1x inside-text">4</strong>
)
the whole table being sort descending based on that value. Means if any other rows having no rating values inside that strong tags in the first cell, the row with some values shows as the final row in the whole table.

What I did wrong here.

Answer

Use order option to specify alternative column to sort. By default, it uses first column even if you disables sorting for that column.
