怎样修改表格

<Columns>
                                <asp:TemplateColumn HeaderText="序号">
                                    <HeaderStyle Width="50px" />
                                    <ItemTemplate>
                                    <%#Container.ItemIndex+1 %>
                                </ItemTemplate>
                                </asp:TemplateColumn>
                                
                                    <asp:BoundColumn DataField=xingming HeaderText='病人姓名'></asp:BoundColumn>
                                    <asp:BoundColumn DataField=binglihao HeaderText='病历号'></asp:BoundColumn>
                                    <asp:BoundColumn DataField=shijian HeaderText='日期'></asp:BoundColumn>
                                    <asp:BoundColumn DataField=feiyong HeaderText='挂号费'></asp:BoundColumn>
 </Columns>
删除“序号”，以病历号排序，应该怎么改？求赐教
