Striking thru a tabular row in LaTeX

Question

Neither ulem nor soul packages allow striking thru a whole row in a tabular environment, eg:

\sout{1,3-Cyclopentadiene    & 161.39    & 148.19    & 155.65    & 153.43    & 154.7     & 5.5  & 118.20} \\

Is there an alternative?

Package xcolor with the table option clashes with package dcolumn so that does not appear to be an option

Answer 1

As a quick and dirty fix you can superpose a row with a \hline by reducing row spacing before and after the line:

\documentclass{article}
\begin{document}
\begin{tabular}{lll}
aaaaa & bbbbb & ccccc \\
11111 & 22222 & 33333 \\ [-1.5ex]
\hline \\ [-1.5ex]
xxxxx & yyyyy & zzzzz \\
\end{tabular}
\end{document}

Answer 2

One can use TikZ to do so :

\usepackage{tikz}
\tikzstyle{every picture}+=[remember picture]
\tikzstyle{na} = [shape=rectangle,inner sep=0pt]

\newcommand{\ptStrikeA}[1]{     % Left 'point' to be striked (A)
    \tikz[baseline=(A.base)]\node[na](A){#1};
  }
\newcommand{\ptStrikeB}[1]{     % Right 'point' to be striked (B)
    \tikz[baseline=(B.base)]\node[na](B){#1};
  }  

\newcommand{\strike}{   % Strike from A to B
    \begin{tikzpicture}[overlay]
        \draw (A.west) -- (B.east);
    \end{tikzpicture}
  }

\begin{document}
    \begin{tabular}{lll}
                    aaaaa & bbbbb & ccccc \\
        \ptStrikeA{11111} & 22222 & \ptStrikeB{33333} \\
                    xxxxx & yyyyy & zzzzz \\
    \end{tabular}
    \strike
\end{document}

This way, you can either strike an entire row, or only part of it. Putting the \strike command outside the environment allows you to embed it into beamer overlays.

To achieve multiple strikethroughs in a single table, rather than declaring more and more commands, you can specify the start/end points dynamically:

\usepackage{tikz}
\tikzstyle{every picture}+=[remember picture]
\tikzstyle{na} = [shape=rectangle,inner sep=0pt]

% end point for strike
\newcommand{\ptStrike}[2]{    
    \tikz[baseline=(#1.base)]\node[na](#1){#2};
}

% draw strike between two endpoints
\newcommand{\strike}[2]{  
    \begin{tikzpicture}[overlay]
        \draw (#1.west) -- (#2.east);
    \end{tikzpicture}
}

\begin{document}
    \begin{tabular}{lll}
        aaaaa & bbbbb & ccccc \\
        \ptStrike{A}{11111} & 22222 & \ptStrike{B}{33333} \\
        xxxxx & yyyyy & zzzzz \\
        \ptStrike{C}{33333333} & 55555555 & \ptStrike{D}{88888888}\\
    \end{tabular}
    \strike{A}{B} % draw strike from A to B
    \strike{C}{D} % draw strike from C to D
\end{document}

You can take it one step further even and avoid needing to redefine names for beginning and endpoints!

\documentclass{standalone}
\usepackage{tikz}
\tikzstyle{every picture}+=[remember picture]
\tikzstyle{na} = [shape=rectangle,inner sep=0pt]

\newcommand{\myStrikeBegin}[1]{%
    \tikz[baseline=(begin.base)]\node[na](begin){#1};
}

\newcommand{\myStrikeEnd}[1]{%
    \tikz[baseline=(end.base)]\node[na](end){#1};
    \begin{tikzpicture}[overlay]
          \draw (begin.north west) -- (end.south east);
    \end{tikzpicture}
}

\begin{document}
    \begin{tabular}{lll}
        aaaaa & bbbbb & ccccc \\
        \myStrikeBegin{11111} & 22222 & \myStrikeEnd{33333} \\
        xxxxx & yyyyy & zzzzz \\
        \myStrikeBegin{33333333} & 55555555 & \myStrikeEnd{88888888} \\
    \end{tabular}
\end{document}

Answer 5

With {NiceTabular} of nicematrix, you can easily strike a row with TikZ by using the nodes created by nicematrix.

\documentclass{article}
\usepackage{nicematrix,tikz}

\begin{document}

\begin{NiceTabular}{lll}[hvlines]
    aaaaa & bbbbb & ccccc \\
    11111 & 22222 & 33333 \\
    xxxxx & yyyyy & zzzzz \\
    33333333 & 55555555 & 88888888 \\
\CodeAfter
   \tikz \draw [red] (2.5-|1) -- (2.5-|last) ; 
   \tikz \draw [thick,red] ([yshift=-4pt]4-|1) -- ([yshift=4pt]5-|last) ; 
\end{NiceTabular}

\end{document}
