在DW里排列的好好的，
可是预览出来，
左右怎么都不能对齐，
请问问题处在哪里呢？
谢谢！
代码如下：
<table width="559" border="0" cellpadding="0" cellspacing="0">
<!--DWLayoutTable-->

<td width="272" height="1"></td>
<td width="17"></td>
<td width="270" rowspan="4" valign="top"><table width="270" border="0" cellpadding="0" cellspacing="0" background="0_index/tupian/wangyetupian/index_img/index_r11_c9.jpg">
<!--DWLayoutTable-->
