Answer 1

<?php
require_once "../smarty/libs/Smarty.class.php";
$smarty = new Smarty;
$smarty->left_delimiter = "{";
$smarty->right_delimiter = "}";
$smarty->template_dir = "./templates";
$smarty->compile_dir = "./templates_c";

$goods_orderby_list = array(
		"1"=>array(
				"1"=>array(
						"number"=>"11"
						),
				"2"=>array(
						"number"=>"12"
				)
				),
		"2"=>array(
				"1"=>array(
						"number"=>"21"
						),
				"2"=>array(
						"number"=>"22"
				)
				)
		);
$category_list = array(
		"1"=>array(
				"id"=>"1"
				),
		"2"=>array(
				"id"=>"2"
				)
		);

$smarty->assign("goods_orderby_list",$goods_orderby_list);
$smarty->assign("category_list",$category_list);
$smarty->display("one.tpl");

{foreach from =$goods_orderby_list  item=goods_orderby}
           <tr>
                  {foreach from =$category_list  item=category}
                  <td align="center">{$goods_orderby[$category.id].number}</td>
                  {/foreach}
                 
           </tr>
{/foreach}

我试了，这样可以，输出：11 12 21 22

你那样写应该对的，不知道$goods_orderby_list是几维数组的，是三维数组是正确的；
