How to make a button stay at a fixed position in ASP.NET

[royboy303]

In my webpage I have following code, basically, a button, two radio buttons and a label,\[code\]<tr> <td class="primary-BL1" style="text-align:right; width:18%"> <asp:Button ID="SubmitButton" runat="server" Text="Submit" onclick="SubmitButton_Click" CssClass="button" /> </td> <td class="primary-BL1" style="text-align:left; width:34%"> <asp:RadioButtonList ID="rblVerification" runat="server" RepeatDirection="Horizontal"> <asp:ListItem http://stackoverflow.com/questions/13748804/Value="V">Verified</asp:ListItem> <asp:ListItem Value="http://stackoverflow.com/questions/13748804/NV">Not Verified</asp:ListItem> </asp:RadioButtonList> </td> <td class="primary-BL1" style="text-align:left; width:48%"> <asp:Label runat="server" ID="CallReasonMessageLabel" CssClass="required"></asp:Label> </td> </tr>\[/code\]When I click the submit button, if the label shows some error message, the position of the button will move to the left a little bit. How should I do to make the button stay in the fixed position? This only happens in IE8, not IE7.
