在以下情况下，Tex4ht如果包含某个包，即使未使用该包，也会生成一个矩阵的列之间没有空格的 HTML 文件。
移除包装后，柱子之间的空隙又显现出来。
这只会影响 tex4ht，而不会影响 pdflatex。
表格型
\documentclass[12pt,notitlepage]{article}%
\usepackage{tabularx} %commenting this off restores the spaces
\begin{document}
\begin{tabular}{p{6in}}
\[
\left[ \begin {array}{cc}
0 & 1 \\
-25 & -4
\end {array}
\right]
\]
\end{tabular}
\end{document}
数组包
\documentclass[12pt,notitlepage]{article}%
\usepackage{array}% http://ctan.org/pkg/array
\begin{document}
\begin{tabular}{p{6in}}
\[
\left[ \begin {array}{cc}
0 & 1 \\
-25 & -4
\end {array}
\right]
\]
\end{tabular}
\end{document}
下列软件包也会导致同样的问题，但这是由于它们array在内部加载了该包： siunitx，ltxtable并且任何其他加载该array包的软件包都会出现上述问题。
如果 Latex 代码在环境之外，则不会出现这些问题tabular。正如我在下面的评论中所说，这是一个来自大型文档的小示例。我使用tabular2 列来帮助我排列文档的布局。左侧是命令，右侧是输出。两者都可以是乳胶代码，如上所示。
答案1
我再次发现了这个问题，我认为你可以用这个版本修复这个问题array.4ht：

变化在于我们不将数组空间设置为零：
% why did we set these variables to zero? it leads to wrong spacing
% in pictures.
% https://puszcza.gnu.org.ua/bugs/?229
% \arrayrulewidth\z@ \doublerulesep\z@
% \arraycolsep\z@ \tabcolsep\z@
结果如下：
