i want to create a table in the datatables which does not have data in the last rows data. i wanna leave it empty with borders. right now i when i 10 rows of data 4on each page. the data get into 3pages where first and second page have 4 rows and when we reach the third page there is only two data and the other space is left blank. i wanna create a table and then fetch data but the datatable is creating the table in my code so. cud anyone suggest how can i leave the last two rows blank and visible.

var dataSet = [];
for(var i = 0; i < data.response.docs.length; i++)
{

    var d = data.response.docs[i];


            var minPrice = d.min_price;
            var minPrice = d.shipping;
            var seller_rating = d.rating;
            var product_rating = d.product_rating;
            var total = minPrice + shipping;
            var ships_on = 'n/a';
            var delivered_by = 'n/a';

            dataSet.push([{ 'url': d.url},
                            total,
                           minPrice + '+' + shipping,
                          ships_on, delivered_by,
                          seller_rating, product_rating]);
        }
        $('#data_table').dataTable( {

                        if ( sReturn != "N/A") {

                            $('#fixed').raty({
                                    readOnly:  true,
                                    start:     val
                                });

                            sReturn = $('#fixed').html();
                            $('#fixed').html("");
                        }
                        return sReturn;
                    }
                },          
        }); 

I just want the last two rows to be visible wheater they have data or not

  if(dataSet != '' || no/4 != 0)
       {

       //alert(no);
        var minPrice = 0;
        var shipping = 0;
        var seller_rating = 0;
        var product_rating = 0;
        var ships_on = 'n/a';
        var delivered_by = 'n/a';   
        var total = minPrice + shipping;
        var a = no%4;
        for(var i=0;i<(4-a);i++)
        {

        dataSet.push([{'title': '', 'url': ''},
                            {'image': '', 'name': ''},
                            '0',
                           '0',
                          'n/a', 'n/a',
                         '0', '0']);
        }
        }
       $('#data_table').dataTable( {
            "aaData": dataSet ,
            "bSort":true,
            "aaSorting": [[0,'desc'],[0,'asc'],[2,'asc'],[2,'desc'],[3,'asc'],[3,'desc'],[4,'asc'],[4,'desc'],[5,'asc'],[5,'desc'],[6,'asc'],[6,'desc'],[7,'asc'],[7,'desc']],
            "iDisplayLength": 4,            
            "bInfo": true,
            "bLengthChange": false,
            "bJQueryUI": true,
            "bPaginate": true,
            "bAutoWidth": false,
            "sPaginationType": "full_numbers",
            "bAutoWidth": true,
            "aoColumns": [
                {   "sTitle": "Seller",
                    "sWidth": "155px",
                    "sClass": "grey" ,
                    "fnRender": function(obj) {
                        var data = obj.aData[ obj.iDataColumn ];
                        return "<a href='"+ data.url +"'>"+ data.title +"</a>";
                    }

                }

Its creating two rows which is not having data and is empty. and will create two empty row. I needed data where in each page thereare 4 data in each page. so i m using it in mutiples of 4.

I don't know about the datatable plugin you have been using however you can pad your dataset with empty values to make it work:

var dataset = ['1','2','3','4','5','6','7','8','9'];
var rowCount = 4;
var mod = dataset.length%rowCount;

if(mod) {
    for(var i=mod; i<rowCount;i++) {
        dataset.push('')   
    }
}
