phplib的嵌套block问题

[Arbow]

phplib具有block功能，可以把一部分代码重复显示。请问能否进行block的嵌套？

模板：1.tpl:
<table border="1">
<!-- BEGIN row -->
<tr>
<!-- BEGIN col -->
<td>{NUM}</td>
<!-- END col -->
</tr>
<!-- END row -->
</table>

php程序代码：
<?
include("./include/template.inc");
$t =new Template(".");
$t->set_file ("fHandle","1.tpl");
$t->set_block ("fHandle","row","rows");
for ($i=1;$i<5;$i++)
{
$t->set_block ("fHandle","col","cols");
for ($j=1;$j<5;$j++)
{
$num=$i*$j;
$code=$i.'*'.$j.'='.$num;
$t->set_var ("NUM","$code");
$t->parse ("cols","row",true);
}
$t->parse ("rows","row",true);
}
$t->parse ("out","fHandle");
$t->p("out");
?>

结果程序输出：
<table border="1">

<tr>
<!-- BEGIN col -->
<td>1*4=4</td>
<!-- END col -->
</tr>

<tr>
<!-- BEGIN col -->
<td>2*4=8</td>
<!-- END col -->
</tr>

<tr>
<!-- BEGIN col -->
<td>3*4=12</td>
<!-- END col -->
</tr>

<tr>
<!-- BEGIN col -->
<td>4*4=16</td>
<!-- END col -->
</tr>

</table>
的页面，可见里层的block没有被执行。



对此请问php高手们phplib能否进行嵌套block？如果，可以，麻烦给出修改后的程序，谢谢～～50分等着你：）
