如何将 figure/table 对齐到 XSL-FO 页面的顶部或底部 (FOP 2.1)
How to align figure/table to the top or bottom of the page in XSL-FO (FOP 2.1)
如果图或table有点大，将它们移动到页面的顶部或底部真的很合适table。通过重复 headers 将 table 重排到下一页的能力很棒，但并不总是我想要的。如果 table 或图形非常适合页面并且不一定锚定到段落，则没有理由重排它。最好让它“漂浮”在页面body之外。
This answer 真的很鼓舞人心，但我不确定如何将它应用到我的案例中。如果我能根据 table.
的 @rendition 属性来做，我会很高兴

正如 Tony Graham 评论的那样，FOP 不支持 before floats yet（奇怪的是，它会在没有警告的情况下默默地吞下它们）。
但是，您可以使用脚注代替将您的表格放在引用它们的页面底部。如果我没记错的话，FOP 倾向于将脚注完整地放置而不是添加更多 "flowing" 内容，因此结果 应该 是预期的结果。

结果输出：
使用脚注的缺点是对脚注放置的限制比浮动之前的限制更严格（可以放在页面以下 他们的锚点区域，根据 section 6.12.2 of the recommentation)，因此如果输入在一系列段落中引用了许多表，则可能存在布局问题（页面中的空白区域）。
