Arrange Table In Center With Different Column in website?

Table to arrange in center, has one row has one more column than other row (see screenshot). Please help me to arrange in center of screen, except red color font to be fixed at right side.

Here is code..

[![<table>
        <tr>
            <td>
                <asp:Label runat="server">Select Country : </asp:Label>
            </td>
            <td>
                <asp:DropDownList runat="server">
                    <asp:ListItem>America</asp:ListItem>
