这是初学建立的框架，可是预览和实际老是有出入，看代码也没发现问题呀，实在奇怪，难道是嵌套问题，请版主看看，谢谢了。代码如下：
<style type="text/css">
<!--
body {
margin-left: 0px;
margin-top: 0px;
}
.STYLE3 {font-family: "Times New Roman", Times, serif}
-->
</style>
<table width="778" height="732" border="2" align="center" cellpadding="0" cellspacing="0" bordercolor="#999999">
<tr>
<td height="76" valign="top" bordercolor="#666666" width=100%> </td>
</tr>
<tr>
<td height="8" valign="top" bordercolor="#FF0000" bgcolor="#FFFFFF" width=100%></td>
</tr>
<tr>
<td height="20" valign="top" bordercolor="#666666" ><table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr width="100%">
