如何使用 xsl fo 创建具有动态列数的表。列数因每个输入文件而异，但对于单个输入文件是固定的。

这是一个示例 xml

<root>
<ColNo>3</ColNo>
<Objects>
<object id="1">
 <prop1 old="5" new="7">
 <prop2 old="2" new="1">
 <prop3 old="3" new="6">
</object>
</Objects>
</root>

我想要一张像下面这样的桌子

Obj1
------------------------------------------
 prop1     | prop2          | prop3 
-------------------------------------------
old | new  |  old | new     | old  | new
-------------------------------------------
5   | 7    |  2   |  1      | 3    | 6

我遇到了number-columns-repeated属性..但无法理解如何使用它..

如果有更好的方法，也请告诉我。

谢谢。

您没有说明您尝试了多少，但我怀疑没有太多，因为输入数据格式不正确。而且你也没有说明多行数据是如何表示的，所以我在下面通过修改数据添加了额外的信息进行了猜测。

下面是一个完整的解决方案。它使用了两种可用的行填充技术，类似于我在课堂上使用的插图（以及练习）。

当我通过符合要求的 XSL-FO 处理器运行下面的输出时，我得到了您所要求的表格。

t:\ftemp>type table.xml 
<root>
<ColNo>3</ColNo>
<Objects>
<object id="1">
 <prop1 old="5" new="7"/>
 <prop2 old="2" new="1"/>
 <prop3 old="3" new="6"/>
 <prop1 old="15" new="17"/>
 <prop2 old="12" new="11"/>
 <prop3 old="13" new="16"/>
</object>
</Objects>
</root>

t:\ftemp>call xslt table.xml table.xsl table.fo 

t:\ftemp>type table.fo
