文本框和图像按钮的对齐方式（asp.net）

Question

这是我的UI输出

我可以将日期文本框和图像按钮直接对齐，就像任务名称下拉列表和添加图像按钮一样吗？

这是我的asp.net代码

<table id="fix">
                    <tr>
                        <td >
                            <asp:Label ID="lblUserName" runat="server" Text="Label" style="width:80px;"></asp:Label>
                        </td>
                        <td>
                            <asp:DropDownList ID="DropDownList1" runat="server" Width="200px" Style="width: 150px" DataSourceID="SqlDataSource1" DataTextField="USERNAME" DataValueField="USERNAME" AutoPostBack="True" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">

                            </asp:DropDownList>
                            <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:SOConnectionString %>" ProviderName="<%$ ConnectionStrings:SOConnectionString.ProviderName %>" SelectCommand="SELECT USERNAME FROM USERMASTER WHERE USERSTATUS = 1 AND USERACCESSRIGHTS = 'Non-Administrator' ORDER BY USERNAME"></asp:SqlDataSource>
                        </td>
                        <td>

                        <td>
                            &nbsp;</td>
                    </tr>

                    <tr>
                        <td style="width: 100px;">

                        <td>

                        </td>
                    </tr>
                    <tr>
