table-default.html和table-dtd.html 的区别是多了一行:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
在以下代码前面:
<table align="center" border="0" cellpadding="0" cellspacing="0" width="960">
<tbody><tr>
<td bgcolor="#00ff00">Up</td>
</tr>
</tbody></table>
<table align="center" border="0" cellpadding="0" cellspacing="0" width="960">
<tbody><tr>
<td bgcolor="#3f3f3f"><img src="http://dl.dropboxusercontent.com/u/467352/Screenshots/line.jpg" height="5" width="960"></td>
</tr>
</tbody>
</table>
<table align="center" border="0" cellpadding="0" cellspacing="0" width="960">
<tbody><tr>
<td bgcolor="#0000ff">Down</td>
</tr>
</tbody></table>
