我有以下乳胶文件：
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{longtable}
\begin{document}
\begin{longtable}{|ll|}
%\toprule
converter & version \\
%\midrule
%\midrule
\endfirsthead%
%\bottomrule
\caption{Converters and the version this document refers to }%\label{tab:versions}
\endlastfoot%
\texttt{pdflatex} & \texttt{pdfTeX 3.141592653-2.6-1.40.24} \\% chktex 8
\texttt{xelatex} & \texttt{XeTeX 3.141592653-2.6-0.999994} \\% chktex 8
\texttt{lualatex} & \texttt{LuaHBTeX, Version 1.15.0} \\
\end{longtable}
\end{document}
使用 capption i 生成错误htlatex test：
! Missing } inserted.
<inserted text>
}
l.190 ...and the version this document refers to }
%\label{tab:versions}
?
! Emergency stop.
<inserted text>
}
l.190 ...and the version this document refers to }
%\label{tab:versions}
No pages of output.
Transcript written on test.log.
如果我注释掉标题，问题就会消失，并且输出text.html看起来不错。
也许我应该提到日志中还发生了以下事情：
(/usr/share/texmf/tex/generic/tex4ht/tex4ht.sty
l.864 --- TeX4ht warning --- nonprimitive \everypar ---
--- needs --- tex4ht test ---
这个测试文件是从一个更大的文件中提取出来的，我敢打赌，它在早期版本中是有效的...我使用 texlive。
我感觉有些配置不对。谁能帮忙？

尝试这个版本longtable.4ht：
