我注意到该\thetable命令返回了错误的环境数字longtable。我在表格标题中包含了短语“上一页继续”，并在其前面添加了\tablename\ \thetable\ \textemdash\。在编译文档时，我看到表 1 在第二页上被称为表 2。单面表格不会发生这种情况，如我的 MWE 中所示。我可以轻松解决这个问题并减少多面表格中的计数器，但我认为这不是最好的主意。找到导致此行为的错误会更好。
有什么想法吗？

如果使用\caption而不是\captionof长表，计数器将按预期工作：
\documentclass{article}
\usepackage{longtable, tabu, booktabs, caption, parskip}
\begin{document}
\begin{table}[h]
\caption{A floating table}

\midrule
foo & bar & bacon & eggs\\
foo & bar & bacon & eggs\\
foo & bar & bacon & eggs\\
foo & bar & bacon & eggs\\
foo & bar & bacon & eggs\\
foo & bar & bacon & eggs\\
foo & bar & bacon & eggs\\
\bottomrule
\end{tabu}
\end{table}
That was table \thetable.
\captionof{table}{A non-floating table}
