页脚按钮的Gridview colspan

Question

我有一个网格视图，目前看起来像这样：

我想使用显示添加新行的按钮制作单元格，以跨越其上方按钮的 2 列。

我还想在其他 4 列上添加文本框，并有效地使该行成为“添加用户行”。我是初学者，仍在试验中，详细的解释将非常有帮助。

这是html代码：

<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true"
    CodeFile="Admin.aspx.cs" Inherits="_Default" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">
    <link href="css/admin.css" rel="stylesheet" />
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">
    <header class="grid_9">פאנל מנהל</header>
    <div class="grid_9 block_head">
        טבלת משתמשים
    </div>
    <div class="block grid_9" id="user_block" runat="server">
        <asp:GridView ID="gdview" OnRowEditing="gdview_RowEditing" DataKeyNames="id" AutoGenerateColumns="False"
            CssClass="Grid" OnRowUpdating="gdview_RowUpdating" OnRowCancelingEdit="gdview_RowCancelingEdit"
            runat="server" HeaderStyle-CssClass="tableheader" OnRowDeleting="gdview_RowDeleting" OnRowCreated="RowCreated"
            ShowFooter="true">
            <Columns>
                <asp:BoundField HeaderText="מספר מזהה" DataField="id" ReadOnly></asp:BoundField>
                <asp:BoundField HeaderText="שם משתמש" DataField="username"></asp:BoundField>
                <asp:BoundField HeaderText="סיסמא" DataField="password"></asp:BoundField>
                <asp:BoundField HeaderText="אימייל" DataField="email"></asp:BoundField>

                <asp:CommandField ShowEditButton="True" CancelText="בטל" UpdateText="עדכן" EditText="ערוך"></asp:CommandField>

                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:LinkButton ID="lnkdel" runat="server" Text="מחק" CommandName="Delete"></asp:LinkButton>
                    </ItemTemplate>
                </asp:TemplateField>

                <asp:TemplateField>
                    <FooterTemplate>
                        <asp:Button ID="ButtonAdd" runat="server" Text="Add New Row" />
                    </FooterTemplate>
                </asp:TemplateField>

            </Columns>
        </asp:GridView>
    </div>
</asp:Content>

谢谢！
