网上看到过这样的效果，现提供制作的Html代码：

<table cellspacing=0 cellpadding=0 width=350 align=center border=0>
<tbody>
<tr>
<td valign=bottom align=right width=347 rowspan=2>
<table cellspacing=0 cellpadding=0 width="100%" border=0 #333333 1px solid; BORDER-TOP: #333333 1px solid; BORDER-LEFT: #333333 1px solid; BORDER-BOTTOM: #333333 1px solid;">
<tbody>
<tr>
<td colspan="4" height="20"> </td>
</tr>
<tr>
<td colspan="3" nowrap height="30" width="56">
