template.html 的主要代码

1<html>
2 <head>
3    <title>$htmlkey[0]</title>
4    <meta http-equiv=\"Content-Type\" content=\"text/html; charset=gb2312\">
5 </head>
6 <body >
7    <table $htmlkey[1] height=\"100%\" border=\"0\" width=\"100%\" cellpadding=\"10\" cellspacing=\"0\" bgcolor=\"#eeeeee\" style=\"border:1px solid #000000\">
8       <tr>
9       <td width=\"100%\" valign=\"middle\" align=\"left\">
10          <span style=\"color: $htmlkey[2];font-size: $htmlkey[3]\">$htmlkey[4]</span>
11       </td>
12       </tr>
13    </table>
14 </body>
15</html>
