我需要交替着色的行，但颜色要双倍。也就是说，我需要 2-3 行是灰色，4-5 行是白色，6-7 行是灰色，等等。

我应该怎么办？

一种可能的解决方案是使用\hiderowcolors/ \showrowcolors：

\documentclass[12pt]{article}
\usepackage[ paperwidth=8.27in, paperheight=11.69in]{geometry}
\usepackage{booktabs, siunitx}
\usepackage[svgnames,table]{xcolor}
\usepackage{longtable}
\usepackage{multirow}
\newcommand{\mytablecolor}{\rowcolors{2}{gray!10}{gray!10}}

\begin{document}
    \begin{center}
        \begin{tabular}{cc}
            \toprule
            \mytablecolor
            \begin{tabular}{cccc}
                \multicolumn{4}{c}{Replication I}\\
                \midrule
                a & bc & 1 & d\\
                24.0 & 15.8 & 17.5 & 20.8 \\
                \hiderowcolors ad & c & bd & b \\
                27.5 & 24.3 & 22.5 & 18.3 \\
                \showrowcolors abc & cd & ab & ac \\
                21.5 & 15.5 & 26.2 & 27.5 \\
                \hiderowcolors abcd & acd & bcd & abd  \\
