Using the 1.4 version, I have experienced the ghost (blank) extra cells in my table in the following configuration:
DataTables is enabled, and IE9 is used (this is the case for the Report Viewer under Windows 2008).

Actually it is a bug from IE9 and you can have the detail in
https://www.datatables.net/forums/discussion/5481/bug-ghost-columns-when-generating-large-tables.

The workaround I made is just to update the following JavaScript in the C:\ProgramData\Seal Repository\Views\Model.cshtml file (I just added 3 lines at the end):
Code:
<script type="text/javascript">
    $(document).ready(function () {
        var dataTables = $('#@View.ViewId .data_table');
        try {
            if (dataTables != null && @Helper.ToJS(View.GetBoolValue("data_tables_enabled")) && !@Helper.ToJS(Report.PrintLayout))
            {
                dataTables.dataTable({
                    "sDom": '<"dataTableTop"lfpri>t',
                    "aoColumnDefs": [{ "bSortable": false, "aTargets": ["firstcell"]}],
                    "oLanguage": {
                        "sProcessing": "@Report.Translate("Processing...")",
                        "sLengthMenu": "@Report.Translate("Show _MENU_ rows")",
                        "sZeroRecords": "@Report.Translate("No row")",
                        "sInfo": "@Report.Translate("Showing _START_ to _END_ of _TOTAL_")",
                        "sInfoEmpty": "@Report.Translate("Showing 0 to 0 of 0")",
                        "sInfoFiltered": "@Report.Translate("(filtered from _MAX_)")",
                        "sInfoPostFix": "",
                        "sSearch": "@Report.Translate("Filter:")",
                        "oPaginate": {
                            "sFirst": "|&lt;",
                            "sPrevious": "&lt;&lt;",
                            "sNext": ">>",
                            "sLast": ">|"
            }
            },
                    "bSort": @Helper.ToJS(View.GetBoolValue("data_tables_sort_enabled")),
                    "aaSorting": [],
                    "bPaginate": @Helper.ToJS(View.GetBoolValue("data_tables_pagination_enabled")),
                    "sPaginationType": "full_numbers",
                    "iDisplayLength": @View.GetValue("data_tables_pagination_size"),
                    "bInfo": @Helper.ToJS(View.GetBoolValue("data_tables_show_information")),
                    "bFilter": @Helper.ToJS(View.GetBoolValue("data_tables_filter_enabled")),
                    "bProcessing": @Helper.ToJS(View.GetBoolValue("data_tables_show_processing")),
                    "bAutoWidth": false
            });
var expr = new RegExp('>[ \t\r\n\v\f]*<', 'g');
var tbhtml = dataTables.html();
dataTables.html(tbhtml.replace(expr, '><'));
        }
    }
    catch (e) { };
    });

</script>


and it seems to work fine...

Actually the previous trick for ghost columns does not work if you a split by page values...in this case all the DataTable are the same !

The best way to fix this problem is to edit the C:\ProgramData\Seal Repository\Views\Model.cshtml file and to remove the carriage return and line feed that are between <th></th> and <td></td> when the main data table is generated.

It is 3 lines (one for the header, one for the body and one for the footer) that you have to changed like this:
Code:
<th class='@className' style='@cell.CellCssStyle'>@Raw(cell.HTMLValue)</th>
<td class='@className' style='@cell.CellCssStyle'>@Raw(cell.HTMLValue)</td>
<td class='cell_value_total' style='@cell.CellCssStyle'>@Raw(cell.HTMLValue)</td>


I made this change for the 1.5 version...
