htlatex 对 \columncolor 给出错误，但对 \rowcolor 没有错误

Question

我有以下文件

\documentclass{article}
\usepackage[table]{xcolor}
\begin{document}


\begin{tabular}{ >{\columncolor[rgb]{0,.6,1}} cc}
  Blue&White\\
  Blue&White
\end{tabular}
\bigskip

\begin{tabular}{cc}
  \rowcolor[rgb]{0,.6,1} Blue&Blue\\
  White&White
\end{tabular}

\end{document}

它可以用 pdflatex 编译，但是当我在其上运行 htlatex 时，出现错误

(/usr/share/texlive/texmf-dist/tex/generic/tex4ht/html4.4ht)
(/usr/share/texlive/texmf-dist/tex/generic/tex4ht/html4-math.4ht))     (./try.aux)
! Argument of \:temp has an extra }.
<inserted text> 
                \par 
l.9   B
       lue&White\\
 ?

我猜测，小于号导致了这个问题，但我该如何解决它呢？

我补充说，Michal 的答案确实解决了问题，\columncolor但如果我将其替换为，我会得到同样的错误\color。所以如果我有

\documentclass{article}
\usepackage[table]{xcolor}
\begin{document}


\begin{tabular}{ >{\color[rgb]{0,.6,1}} cc}
  Blue&White\\
 Blue&White
\end{tabular}

\end{document}

然后我得到错误（我复制了加载新代码前一行的错误colortbl.4ht

(/usr/share/texlive/texmf-dist/tex/generic/tex4ht/html4-math.4ht))
(./colortbl.4ht (/usr/share/texlive/texmf-dist/tex/latex/xcolor/xcolor.sty

<inserted text> 
                \par 
l.7   Blue&
           White\\
? 

我补充说，tex4ht 似乎忽略了颜色定义（没有给出错误消息）。也许这是一个单独的错误？这是一个最小的例子

\documentclass{article}
\usepackage{color}
\definecolor{Blue}{rgb}{0,.6,1}
\begin{document}
\color{Blue} Blue---I don't think so.
\end{document}

Answer 1

这是 colortbl 支持中的一个错误tex4ht，它要求\columncolor规范参数用空格而不是逗号分隔。我们将很快修复该问题，同时，您可以尝试将以下文件另存为colortbl.4ht：

通过稍微扩展的示例，还可以测试其他颜色空间：

\documentclass{article}
% \usepackage[table]{xcolor}
\usepackage{colortbl}
\begin{document}


\begin{tabular}{ >{\columncolor[rgb]{0,.6,1}} cc}
  Blue&White\\
  Blue&White
\end{tabular}
\begin{tabular}{ >{\columncolor[cmyk]{0,.6,1,.4}} cc}
  Blue&White\\
  Blue&White
\end{tabular}
\begin{tabular}{ >{\columncolor[gray]{.6}} cc}
  Blue&White\\
  Blue&White
\end{tabular}
\bigskip

\begin{tabular}{cc}
  \rowcolor[rgb]{0,.6,1} Blue&Blue\\
  White&White
\end{tabular}

\end{document}

您将得到以下结果：

第二个示例产生以下输出：
