在 \tabulary 中使用 \cellcolor

Question

虽然在 中可以工作，但\cellcolorpackage 中的命令似乎colortbl在 环境中不起作用。这是一个最小的例子：tabularytabular

\documentclass[a4paper]{article}

\usepackage[english]{babel}
\usepackage[utf8]{inputenc}
\usepackage{tabulary}
\usepackage{colortbl}

\begin{document}

\begin{tabular}{c}
\cellcolor{green}42
\end{tabular}

\begin{tabulary}{\textwidth}{C}
\cellcolor{green}42
\end{tabulary}

\end{document}

还有什么需要添加，或者有解决方法吗？

Answer 1

tabulary检测colortbl并插入针对该情况的修改后的定义，但在 2001 年\cellcolor“最近”添加：并且未更新以匹配。colortbltabulary

\documentclass[a4paper]{article}

\usepackage{colortbl}
