我无法得到板状的与 tex4ebook 一起工作。其他表格环境工作正常；不幸的是，我正在转换一个现有的项目，该项目相当大并且大量使用 xltabular，我应该尽可能为两个版本保留相同的源代码。MWE：
\documentclass[a5paper,10pt,openright]{book}
\usepackage[a5paper, portrait, margin=2cm]{geometry}
\usepackage[portuguese]{babel}
\usepackage{xltabular}
\begin{document}
\begin{xltabular}
{\textwidth}
{| >{\raggedright\arraybackslash}X | >{\raggedright\arraybackslash}X | }
\hline
1st col & 2nd col \\
\hline
\end{xltabular}
\end{document}
命令行：
tex4ebook -l -f epub3 test.tex
（将 -l 切换为 -x 没有任何区别。）
错误消息：
[STATUS] tex4ebook: Conversion started
[STATUS] tex4ebook: Input file: test.tex
[ERROR] htlatex: Compilation errors in the htlatex run

[ERROR] htlatex: ? 14 LaTeX Error: \begin{document} ended by \end{tabularx}.
[ERROR] htlatex: ? 14 Extra \endgroup.
（重复 3 次）
但是，使用 pdflatex 或 xelatex 进行正常编译可以正常工作。
我一直在阅读文档，但到目前为止我还没能弄清楚发生了什么。我也找不到任何迹象表明 xltabular 环境和 tex4ebook 不兼容。
谢谢。

我刚刚发现这个问题，我最初有点忽略了它。这个配置文件xltabular.4ht应该可以解决这个问题：

它已经包含在 TeX Live 中，因此您只需更新您的发行版即可工作。
