由于您覆盖了内部定义，因此每行只能设置一个\rowstyle。因此您需要组合以下命令：\rowstyle{\color{gray}\transparent{0.5}}
\documentclass[12pt]{article}
\usepackage{transparent}
\usepackage[table]{xcolor}
\makeatletter
\newcommand*{\@rowstyle}{}
\newcommand*{\rowstyle}[1]{% sets the style of the next row
\gdef\@rowstyle{#1}%
\@rowstyle\ignorespaces%
}
\newcolumntype{=}{% resets the row style
>{\gdef\@rowstyle{}}%
}
\newcolumntype{+}{% adds the current row style to the next column
>{\@rowstyle}%
}
\makeatother
\renewcommand{\arraystretch}{1.42}
\setlength{\arrayrulewidth}{0.25mm}
\arrayrulecolor{gray!40}
\begin{document}
\begin{tabular}{|=c|+c|+c|+c|+c|+c|}
\rowcolor[gray]{0.65}\multicolumn{6}{c}{ \textcolor{white}{\scriptsize Meditation} \vspace*{0.2cm}}\\
\hline
\rowstyle{\color{gray}\transparent{0.5}}
1 & 2 & 3 & 4 & 5 & 6\\
\hline
\rowstyle{\color{gray}}7 & 8 & 9 & 10 & 11 & 12 \\
\hline
\end{tabular}
\end{document}
