需要在ASP.NET webform中包装表行和控件

<asp:Table ID="Table1" runat="server">
    <asp:TableRow>
        <asp:TableCell>
            <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
        </asp:TableCell>
        <asp:TableCell>
            <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
        </asp:TableCell>
    </asp:TableRow>
    <asp:TableRow>
        <asp:TableCell>
            <asp:Button ID="Button1" runat="server" Text="Button" />
        </asp:TableCell>
        <asp:TableCell>
            <asp:DropDownList ID="DropDownList1" runat="server">
                <asp:ListItem>Item 1</asp:ListItem>
                <asp:ListItem>Item 2</asp:ListItem>
                <asp:ListItem>Item 3</asp:ListItem>
            </asp:DropDownList>
        </asp:TableCell>
    </asp:TableRow>
</asp:Table>

protected void Button1_Click(object sender, EventArgs e)
{
    string text = TextBox1.Text;
    string selectedItem = DropDownList1.SelectedItem.Text;

    // 在这里添加处理逻辑
}
