我在更改 beamer 中的单元格颜色时遇到了问题。我已加载xcolor，beamer并指定了svgnames和table选项；
\documentclass[xcolor=svgnames,smaller,12pt,table]{beamer}
以下是我尝试改变投影仪中的单元格颜色的方法；
\begin{table}[H]
\centering
\caption{Summary of the differences between open and cloed word classes}
\rowcolors{2}{white}{pink!30}
\begin{tabular}{>{\centering\arraybackslash}p{5cm}>{\centering\arraybackslash}p{5cm}}
Open-class & Closed-class\\
\hline
\cellcolor[yellow]{0.5}Admit new members & Do not admit new members \\
Are numerous & Are few \\
Express "content" & Do not express "content" \\
Carry stress & Rarely carry stress \\
Can be long, e.g. \textit{antidisestablishmentarianism} & Tend to be short, e.g. \textit{the, on} \\
\hline
\end{tabular}
\end{table}
我收到错误消息undefined color model。我检查了 是否yellow是 SVG 颜色，结果是 。我还定义了一个名为 的颜色模型yellow，但这也不起作用。
答案1
\cellcolor{yellow!50}
是正确的语法。我想你的意思是灰色。那么它就是
\cellcolor[gray]{0.5}
gray是颜色模型
