投影儀表格中具有輸入輸出效果的單元格著色（突出顯示）

tag-icon • tag-icon tables beamer highlighting pause cellcolor
投影儀表格中具有輸入輸出效果的單元格著色（突出顯示）

我需要在表格的單元格中進行單元格著色（或突出顯示效果）beamer點擊後（我的意思是，我計劃在該框架中討論一些內容，並且我將在演講結束時強調單元格中的一個數字），並且我嘗試了許多命令，例如\onslide<>、\only<>、\visible<>和新命令\colorbox，但是他們中的任何一個都起作用了。最後，我遇到了一些\rowcolor<>{colorname}程式碼，我嘗試安排這些程式碼（完全不知道 newcommand 結構）用於具有輸入輸出效果的單元格著色，但是出現了問題，所以我收到了這樣的錯誤

放錯地方了\noalign。

它有什麼問題呢？

\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@@}

\noalign從 的定義中刪除該指令\cellcolor：

\documentclass[xcolor=table]{beamer}

\rowcolors{1}{gray!30}{gray!10}

\makeatletter
\def\rowcolor{\noalign{\ifnum0=`}\fi\bmr@rowcolor}
\newcommand<>{\bmr@rowcolor}{%

        {\ifnum0=`{\fi}\@gooble@rowcolor}% 
}

\newcommand{\@gooble@rowcolor}[2][]{\@gooble@rowcolor@}
\newcommand{\@gooble@rowcolor@}[1][]{\@gooble@rowcolor@@}
\newcommand{\@gooble@rowcolor@@}[1][]{\ignorespaces}
