表格页脚不使用Apache FOP进行分页

Question

我正在使用FOP（最新开发版本 - 2.2）从XML生成PDF。 xml由大型复杂结构组成，我无法控制格式或模式。基本上我的问题是，当我在表中有一个长tfoot部分时，表不会创建分页符。当行在tbody部分内时，它会很好地完成，并且我已经开始工作并添加一个＆＃34;继续＆＃34;到表头中的表标题。我希望能够做同样的事情，但在表格页脚部分。 我已经在Stackoverflow和网络上研究了大量的帖子，并尝试了很多不同的场景，但没有一个适合我。我查看过：possible stackoverflow solution和retrieve-table-marker example但它并没有影响我的布局。我已尝试过在各种构造中使用保持在一起的属性的许多其他组合，但没有成功。这是一个小编辑的示例xml文件我测试时删除了很多内容，因此它不是实际文件：

<?xml version="1.0" encoding="UTF-8"?>

我试图在fo：table-footer部分中使用retrieve-table-marker来在页脚中断时检索表标题，但页面永远不会中断。我已经在标记上尝试了检索位置的所有组合而没有任何更改。我还尝试了check-position-table-table属性的所有组合，我不相信它是在最新版本的FOP中实现的，根据：Apache FOP compliance doc

我不明白为什么FOP会破坏tbody部分的表而不是tfoot部分？任何建议或意见将不胜感激。提前谢谢。

我正在编辑这个问题，询问是否有什么东西我在这里不清楚，或者缺少可以让某人回答这个问题的信息或指向我的方向。我已经尝试将overflow属性设置为在表中的各种构造上可见，但没有效果。我还添加了一个屏幕截图，显示了pdf中的问题。
