Beamer: Revealing cells one by one, striking off a list at the same time

Question

The entries in cells need to appear one by one and at the same time content (entire row) in the reference table no. 1 needs to be struck through.

For the table number 2 in the row marked Tasks, the tasks number are picked up from the table number 1. As the task numbers get picked, the corresponding entry (entire row) in the table number 1 needs to be striked through. Also, for the cells which are having multiple task numbers the entries need to appear one by one. For example: \onslide<6->{2,3,4}, the content should appear one by one, first 2, then 3, and 4. How to do this simultaneous striking through in the table 1 (entire row) as tasks get filled in table 2 from table 1?

You shouldn't use the utf8x inputenc option with a current latex distribution — samcarter_is_at_topanswers.xyz, Aug 14 '23 at 07:46

You could use the trick from https://tex.stackexchange.com/a/265728/36296 to strike through rows in your table:

Package tikz Error: I did not find the tikz library 'tikzmark'. I looked for either could be found in the current texmf trees.. \usetikzlibrary{tikzmark}.

@mathslove Do you have https://www.ctan.org/pkg/tikzmark and https://www.ctan.org/pkg/aobs-tikz installed? — samcarter_is_at_topanswers.xyz, Aug 14 '23 at 15:21
@mathslove Your tex distribution seems to be very incomplete. Which tex distribution do you use? — samcarter_is_at_topanswers.xyz, Aug 14 '23 at 15:21
(aobs is not strictly necessary for this answer and I removed it) — samcarter_is_at_topanswers.xyz, Aug 14 '23 at 15:25
Unfortunately, the package tikzmark could not be installed. Please check the log file: /Users/bhawnapriya338/ Library/ Application Support/MiKTeX/texmfs/data/miktex/log/pdflatex.log. This is the main error. — mathslove, Aug 14 '23 at 15:31
@mathslove This sounds very broken. Best ask a new question about your problem to install tikmarks in miktex. — samcarter_is_at_topanswers.xyz, Aug 14 '23 at 15:35
Yes using macOS. Let me check the issue. I will start a new thread if it doesn't get resolve. — mathslove, Aug 14 '23 at 15:51
@mathslove I wouldn't use miktex on macos. Almost all mac users will either use mactex or directly texlive. That's so much better tested. Big advantage of mactex and texlive: they can do a full installation and thus avoid any missing packages error in the future. — samcarter_is_at_topanswers.xyz, Aug 14 '23 at 15:56

Here is a solution with nicematrix. You need several compilations (because of the PGF/Tikz nodes constructed by nicematrix).

       \bottomrule
    \end{tabular}
  \end{table}
    }
\vfill
\end{frame}
\end{document}

The main part of the code is the following command \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

That command \Strike acts by side effect, that is to say that it adds code in the parameter \g_nicematrix_code_after_tl provided by nicematrix (it's a parameter internal but public) and do not do the typesetting directly. That's why we need \only and not \uncover (with \uncover, the rule would always be drawn since it's a side effect).
