改变乳胶中的表格的可见性

Question

假设我有两个表。我想用另一个表替换顶部表，保持第二个表不变。如何在一个框架中执行此操作？代码应该是这样的：

 \begin{table}[visibility on=<{2}>]
  \centering
    \begin{tabular}{|c|c|}
    \hline
         A & B \\
         \hline
         C & D \\
         \hline

    \end{tabular}
\end{table}

但添加[visibility on=<{2}>]似乎没有任何作用。我希望我已经把我的问题说清楚了。

\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usepackage{subfiles}
\usepackage{circuitikz}
\usepackage{tikz}
\usetikzlibrary{arrows,shapes.gates.logic.US,shapes.gates.logic.IEC,calc}
\usetikzlibrary{overlay-beamer-styles} %<-added
\usepackage{multirow}
\usetikzlibrary{positioning}

\usepackage{colortbl}
\usetheme{Madrid}
\setbeamertemplate{itemize items}[square]


\begin{document}
\setbeamercovered{dynamic}

\begin{frame}{Frame Title}
    \begin{table}[]
      \centering
        \begin{tabular}{|c|c|}
        \hline
             A & B \\
             \hline
             C & D \\
             \hline

        \end{tabular}
 \end{table}

\begin{table}[]

        \begin{tabular}{|c|c|}
        \hline
             1 & 2 \\
             \hline
             3 & 4 \\
             \hline

        \end{tabular}

    \end{table}
\end{frame}
\end{document}

Answer 1

visible on(非)技巧visibility on适用于tikzpictures 的元素（当加载 时\usetikzlibrary{overlay-beamer-styles}，就像您所做的那样）。在tikzpictures 之外，您只需要\only。

\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usepackage{subfiles}
\usepackage{circuitikz}
\usepackage{tikz}
\usetikzlibrary{arrows,shapes.gates.logic.US,shapes.gates.logic.IEC,calc}
\usetikzlibrary{overlay-beamer-styles} %<-added
\usepackage{multirow}
\usetikzlibrary{positioning}

\usepackage{colortbl}
\usetheme{Madrid}
\setbeamertemplate{itemize items}[square]


\begin{document}
\setbeamercovered{dynamic}

\begin{frame}{Frame Title}
\only<2>{\begin{table}[]
      \centering
        \begin{tabular}{|c|c|}
        \hline
             A & B \\
             \hline
             C & D \\
             \hline

        \end{tabular}
 \end{table}}

\begin{table}[]

        \begin{tabular}{|c|c|}
        \hline
             1 & 2 \\
             \hline
             3 & 4 \\
             \hline

        \end{tabular}

    \end{table}
\end{frame}
\end{document}
