I used the code posted in this thread to highlight cells in a table:
\documentclass[xcolor=table]{beamer}
\rowcolors{1}{gray!30}{gray!10}
\makeatletter
\def\rowcolor{\noalign{\ifnum0=`}\fi\bmr@rowcolor}
\newcommand<>{\bmr@rowcolor}{%
\alt#1%
{\global\let\CT@do@color\CT@@do@color\@ifnextchar[\CT@rowa\CT@rowb}%
{\ifnum0=`{\fi}\@gooble@rowcolor}%
}
\newcommand{\@gooble@rowcolor}[2][]{\@gooble@rowcolor@}
\newcommand{\@gooble@rowcolor@}[1][]{\@gooble@rowcolor@@}
\newcommand{\@gooble@rowcolor@@}[1][]{\ignorespaces}
\makeatother
\makeatletter
\def\cellcolor{{\ifnum0=`}\fi\bmr@cellcolor}
\newcommand<>{\bmr@cellcolor}{%
\alt#1%
{\global\let\CT@do@color\CT@@do@color\@ifnextchar[\CT@rowa\CT@rowb}%
{\ifnum0=`{\fi}\@gooble@cellcolor}%
}
\newcommand{\@gooble@cellcolor}[2][]{\@gooble@cellcolor@}
\newcommand{\@gooble@cellcolor@}[1][]{\@gooble@cellcolor@@}
\newcommand{\@gooble@cellcolor@@}[1][]{\ignorespaces}
\makeatother
\begin{document}
\begin{frame}{The MWE}%
\only<2>{\rowcolors{1}{blue!30}{blue!10}}
\only<1,3>{\rowcolors{1}{gray!30}{gray!10}}
\begin{center}
\begin{tabular}{cc}
A & B \\
A & B \\
A & B \\
\rowcolor<4>{green} C & D \\
\rowcolor<4,5>{yellow} E & F \\
\rowcolor<4-6>{green} G & H \\
\rowcolor<6>{red} Y & S \\
A & B \\
\end{tabular}
\end{center}
\par
\visible<1>{Testing default row colouring ... \\}
\visible<2,3>{Testing change of default colors ...\\}
\visible<4-6>{Testing in-out of custom colors ...\\ (caution: The order of defaults colors can change)\\}

\end{frame}
\begin{frame}{Cell Coloring with In-out Effects}
\begin{center}
\begin{tabular}{cc}
A & B \\
C & \cellcolor<3>{green} C \\
D & E \\
F & G \\
\end{tabular}
\end{center}
\end{frame}
\end{document}
But if I change the last frame to
\begin{frame}{Cell Coloring with In-out Effects}
\begin{center}
\begin{tabular}{cc}
A & B \\
\cellcolor<3>{green} C & C \\
D & E \\
F & G \\
\end{tabular}
\end{center}
\end{frame}
then the whole second row gets highlighted. Can somebody tell me how to redefine \cellcolor above to make sure that only one cell will be highlighted?
\cellcolor
doesn't work as expected. Use\cellcolor<3>{green} C & \cellcolor<3>{gray!10} C
as a workaround.\rowcolor
? So it sets it for the whole row or the remainder of the row, depending on where you put the command.
