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。
以下是xml示例
<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>
我想要一张如下表格
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，请告诉我。
感谢。

你没有表明你已经尝试了多少，但我怀疑并不多，因为输入数据不是很好。而且您也没有说明如何表示多行数据，所以我通过修改添加其他信息的数据来猜测。
随后是完整的解决方案。它使用了两种可用的行填充技术，类似于我在教室中使用的插图（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，我按照你的要求概述了表格。
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
