提供了个EmptyDataTemplate，可以把header的样式构造到里面去

<asp:GridView ID="grdvList" runat="server" AutoGenerateColumns="False" CssClass="DataGrid" Width="720px"
                       DataKeyNames="ROW_REF_ID" OnRowCommand="grdvList_RowCommand" AllowPaging="True" AllowSorting="True"
                         PageSize="5" OnPageIndexChanging="grdvList_PageIndexChanging" OnSorting="grdvList_Sorting">
                        <HeaderStyle CssClass="grid_head" />
                        <RowStyle CssClass="grid_row" />
                        <SelectedRowStyle CssClass="grid_row_selected" />
                        <Columns>
                            <asp:BoundField HeaderText="Action Code" DataField="ACTION_CODE" SortExpression="ACTION_CODE" >
                                <HeaderStyle Width="200px" />
                            </asp:BoundField>
                            <asp:BoundField HeaderText="Description" DataField="ACTION_DESCRIPTION" SortExpression="ACTION_DESCRIPTION" />
                            <asp:ButtonField HeaderText="Detail" CommandName="Detail" Text="<img src="../Images/BMG_icon_detail.GIF" alt='Detail'; border=0>" >
                                <HeaderStyle Width="45px" />
                            </asp:ButtonField>
                            <asp:ButtonField HeaderText="Delete" CommandName="InActive" Text="<img src="../Images/BMG_icon_delete.GIF" border=0; alt='delete'>">
                                <HeaderStyle Width="45px" />
                            </asp:ButtonField>
                            <asp:ButtonField HeaderText="Active" CommandName="Active" Text="<img src="../Images/BMG_icon_detail.GIF" border=0; alt='active'>">
                                <HeaderStyle Width="45px" />
                            </asp:ButtonField>
                            <asp:BoundField HeaderText="ROW_REF_ID" DataField="ROW_REF_ID" Visible="False" />
                         </Columns>
                         <EmptyDataTemplate>
                            <table frame="void" cellspacing="0" cellpadding="0" border="1" style="width:720px;border-collapse:collapse;">
                             <tr class="grid_head">
                              <th scope="col" style="width:200px;">Action Code</th>
                              <th scope="col">Description</th>
                              <th scope="col" style="width:45px;">Detail</th>
                              <th scope="col" style="width:45px;">Delete</th>
                          </tr>
                          <tr class="grid_row">
                              <td colspan="4" align="right">1</td>
                          </tr>
                            </table>
                         </EmptyDataTemplate>
                    </asp:GridView>
