分页符在每一页上都有效
但它对第 11 页不起作用
当我删除下表时，一切正常：
\begin{longtable}[c]{| c | c |}
\caption{Determined damping factors in experiments in the air}\\
\hline
Run & Damping factor in 1/s \\
\hline
\endfirsthead
\endhead
\hline
\endfoot
1 & 6,503 * \(10^{-3}\)\\
2 & 4,392 * \(10^{-3}\)\\
3 & 3,900 * \(10^{-3}\)\\
\end{longtable}
我已经搜索该问题很长时间但未能找到解决方案。
答案1
如果我使用 latex3 github 的 longtable4.14 分支中的 longtable 开发版本，您的示例会有更好的分页符
这个问题本质上是这个问题的重复（以及其他问题）
longtabu 和 floats：带有 floats 的页面上的表格分隔符错误
我希望在某个时候更新 longtable，但有一些兼容性问题需要解决

问题确实出在长表上。用 tabluar 表替换它，现在一切正常。
