Getting your jquery datatable to sort DESC by first column. Or set another column as default sort

I tried to figure it out for several hours now, and this is not happening. When I load my table, I need it to sort desc in the first column. Here's what I got out of luck.

/** * Makes the table in the tabs for reports * * @param array Holds the data for datatable. **/ var makeTabTable = function(tableData){ $("#tab_active_reg").dataTable({ bJQueryUI : true, bDestroy : true, aoColumns : [ {"sTitle" : "Seen", "sWidth" : "50px", "asSorting": [ "desc"]}, {"sTitle" : "Sold", "sWidth" : "50px"}, {"sTitle" : "Name", "sWidth" : "240px"} ], aaData : tableData }); $('.tabsComponent').find('.fg-toolbar').empty(); };

just add this option to the dataTable() call:

 aaSorting : [[0, 'desc']]

so in your case:

  $("#tab_active_reg").dataTable({ bJQueryUI : true, bDestroy : true, aaSorting : [[0, 'desc']], aoColumns : [ {"sTitle" : "Seen", "sWidth" : "50px"}, {"sTitle" : "Sold", "sWidth" : "50px"}, {"sTitle" : "Name", "sWidth" : "240px"} ], aaData : tableData });

as you can see, this is an array from [colnumber, sortdirection] , so you can specify a few.

I have a simpler answer according to the latest Datatable docs.

For example, if you want to sort the 4th column of the data table in descending order by default Page Load , use this code.

enter image description here

 $(document).ready( function () { var table = $('#example').DataTable({ //We are simply using order property which is an array of array so multiple columns can be ordered like this. "order": [ [3, 'desc'], ] }); } );
