新建dedecms   htm 模板： body标签中：
{dede:arclist limit=’0,5′ titlelen=’50’}

<table width=”100%” border=”0″ cellspacing=”10″ cellpadding=”0″>

<tr  style=”background:#cccccc;” height=”200″>

<td width=”20%”>  <a href=”[field:arcurl/]”>[field:title/]</a> </td>
<td width=”30%”>[field:infos/]</td>
<td width=”50%”> <table width=”100%” border=”0″ cellspacing=”0″ cellpadding=”0″>
<tr>
<td>  <span id=”diggNum[field:id/]”><a href=”javascript:location.reload()” onclick=”javascript:postDigg(‘good’,[field:id/])”><img src=”/zt/da/zc.jpg” border=”0″></a><br><br>

    <a href=”javascript:location.reload()” onclick=”javascript:postDigg(‘bad’,[field:id/])”><img src=”/zt/da/fd.jpg” border=”0″></a></span>
</td>
<td> 赞成：（[field:goodpost/]票）<br><br>
