如何使用 make4ht 和 siunitx 为 threeparttable 制作 odt

Question

为了实现此功能，需要修复 TeX4ht 中的几个问题。

首先，Siunitx 支持存在两个问题。一个是该tight-spacing选项会导致编译错误，另一个是由S表格中的列引起的，因为它导致表格完全混乱。这两个问题都可以使用此配置文件修复siunitx.4ht：

该软件包还存在另一个问题mhchem。它分发了自己的配置文件，mhchem.4ht其中包含硬编码的 HTML 元素。因此，化学元素不会显示在 ODT 输出中。此版本mhchem.4ht应该可以解决该问题：

还有一些额外的 HTML 标签，您需要使用此配置文件将其删除config.cfg：

\RequirePackage{color} 
\Preamble{xhtml}
\Configure{mhchemce}{}{}
\Configure{mhchemcf}{}{}
\begin{document}
\EndPreamble

编译使用：

$ make4ht -c config.cfg -f odt Test.tex

结果如下：
