Beamer：逐个显示单元格，同时划掉一个列表

单元格中的条目需要逐个出现，同时参考表格 1 中的内容（整行）需要被删除。

对于表格 2 中的行标有任务，从表格 1 中选取任务编号。选取任务编号时，需要删除表格 1 中对应的条目（整行）。此外，对于具有多个任务编号的单元格，条目需要逐一出现。例如：\onslide<6->{2,3,4}，内容应该逐一出现，首先是 2，然后是 3，然后是 4。如何在从表格 1 填充表格 2 中的任务时同时删除表格 1（整行）中的任务？

你可以使用https://tex.stackexchange.com/a/265728/36296删除表中的行：

这是一个使用 的解决方案nicematrix。您需要进行多次编译（因为 构建了 PGF/Tikz 节点nicematrix）。

\documentclass[aspectratio=169]{beamer}            
\usepackage[english]{babel}

{
  \usetheme{default}                
  \usecolortheme{rose}              
  \usefonttheme{default}                
  \setbeamertemplate{caption}[numbered] 
  
}

\usepackage{fontawesome}
\usepackage{charter} 
\usepackage{pdflscape}
\usepackage{booktabs}
\usepackage[font=scriptsize]{caption}

\usepackage{nicematrix,tikz}


\ExplSyntaxOn
\newcommand<> { \Strike }  
  { 
    \only#1
      {
        \tl_gput_right:Nx \g_nicematrix_code_after_tl
          { \mathslove_strike:n { \arabic { iRow } } }
      }
    \ignorespaces
  }
\cs_new_protected:Nn \mathslove_strike:n
  { \tikz \draw ([yshift=2pt]#1-1.south~west) -- ([yshift=2pt]#1-3.south~east) ; } 
\ExplSyntaxOff


% In {NiceTabular} of nicematrix, the rules drawn by "|" are 
% never broken, even when using \toprule, etc. of booktabs.
% The following column type behaves as standard "|" of {tabular}.
\newcolumntype{I}{!{\vrule}}


\begin{document}

\setbeamertemplate{frametitle}[default][center]

\begin{frame}

  \begin{table}
     \tiny
     \caption{Feeding table}
     \begin{NiceTabular}{cIcIc}

          \Strike<15-> 11 &  6 & 13 \\
          \Strike<16-> 12 &  7 &  7 \\
        \bottomrule
     \end{NiceTabular}
  \end{table}

  \begin{itemize}[<+|+->]
    \item Method:
    \item From the available tasks, choose the task for which the sum of following task times is the longest. 
  \end{itemize}   

  \uncover<3->
    {
  \begin{table}
    \caption{Data picked up from feeding table}
    \centering
    \tiny
    \begin{tabular}{l | m{1cm} | m{1cm} | m{1cm} | m{1cm} | m{1cm} | m{1cm} }
       \toprule
         Station & 1 & 2 & 3 & 4 & 5 & 6 \\
       \midrule
         Tasks &\uncover<+->{1} &\uncover<+->{2}\uncover<+->{,3}\uncover<+->{,4} & \uncover<+->{6}\uncover<+->{,5}\uncover<+->{,9}& \uncover<+->{7}\uncover<+->{,8} & \uncover<+->{10}\uncover<+->{,11} & \uncover<+->{12} \\
       \bottomrule
    \end{tabular}
  \end{table}
    }

\vfill

\end{frame}

\end{document}

上述代码的输出结果如下：

代码的主要部分是以下命令\Strike。

\ExplSyntaxOn
\newcommand<> { \Strike }  
  { 
    \only#1
      {
        \tl_gput_right:Nx \g_nicematrix_code_after_tl
          { \mathslove_strike:n { \arabic { iRow } } }
      }
    \ignorespaces
  }
\cs_new_protected:Nn \mathslove_strike:n
  { \tikz \draw ([yshift=2pt]#1-1.south~west) -- ([yshift=2pt]#1-3.south~east) ; } 
\ExplSyntaxOff

该命令的\Strike作用是副作用，也就是说它在\g_nicematrix_code_after_tl提供的参数中添加代码nicematrix（它是一个内部但公开的参数），而不是直接进行排版。这就是为什么我们需要\only而不是\uncover（使用\uncover，规则将始终被绘制，因为它是一个副作用）。
