我正在使用 tex4ebook 生成 .epub。编译过程中出现两组错误，均与解析包含表格（不平衡或意外标签）的 html 文件有关。如能提供任何有关如何解决这些错误的提示，我将不胜感激。

local function mwe_parsing(s)
local status, obj = pcall(function()
return dom.parse(s)
end)
if not status then
log:warning("HTML parsing failed")
log:warning(obj)
return s
end
obj:traverse_elements(function(el)
end)
-- serialize the DOM object back to HTML
return obj:serialize()
end
local process = filter {mwe_parsing}
Make:match("html$", process)
Make:match("html$", "tidy -m -xml -utf8 -q -i ${filename}")
Make:htlatex {}
我在下面包含了编译期间生成的输出。如果我注释掉\begin{center}和\end{center}，第一组错误就会消失。如果我注释掉\part{B}或，\noindent第二组错误就会消失。

答案1
在某些情况下，环境似乎tabularx不会关闭上一段。使用以下配置文件可以很容易地修复此问题：
\Preamble{xhtml}
\ConfigureEnv{tabularx}{\ifvmode\IgnorePar\fi\EndP}{}{}{}
\begin{document}
\EndPreamble
它配置tabularx环境以在输出标签之前关闭前一段<table>。
以下是原始输出：
<!--l. 7--><p class="noindent" >
<table id="TBL-3" class="tabular"
这是固定输出：
<p class='noindent'></p>
<table id='TBL-3' class='tabular'>
