Question

I am using the below jQuery to sort(descending) table on page load. It is working only after I click the arrows for descending or ascending.But,my requirement was to sort the table descending on page load.Any help is appreciated.

$(document).ready(function() { 
oTable = $('#personsList').dataTable({
                    "bJQueryUI": true,
                    "sPaginationType": "full_numbers",
                    "iDisplayLength": 25,
                    "aLengthMenu": [25, 50, 100, 150],
                    "aaSorting": [],                    
                    "bPaginate": false              
                });

You should use that aaSorting parameter to initialize sorting on a specific column.

Below code sorts 1st column asc.

           $(document).ready(function() { 
                 oTable = $('#personsList').dataTable({
                "bJQueryUI": true,
                "sPaginationType": "full_numbers",
                "iDisplayLength": 25,
                "aLengthMenu": [25, 50, 100, 150],
                "aaSorting": [[0,'asc']],      //Sorts 1st column asc              
                "bPaginate": false              
            });
