Link to test case:
I am opening my datatable into modal popup.

var table = $('#<%= GrdHelpingWindow.ClientID%>').prepend($("<thead></thead>").append($("#<%= GrdHelpingWindow.ClientID%>").find("tr:first"))).DataTable({
                    destroy: true,
                    pagingType: "first_last_numbers",
                    scrollX: false,
                    scrollCollapse: false,
                     
                });
