给方格表涂色

我有一张方格表（https://tex.stackexchange.com/a/49751/112272)。我想给单元格着色。我该怎么做？我使用了 colortbl 包，但是不起作用。

\documentclass{article}
\usepackage{array}
\usepackage{calc}
\usepackage{xcolor}
\usepackage{colortbl}

\newlength\celldim
\newlength\fontheight
\newlength\extraheight
\newcounter{sqcolumns}

\newcolumntype{S}{
 @{}
 >{\centering \rule[-0.5\extraheight]{0pt}{\fontheight + \extraheight}%
 \begin{minipage}{\celldim}\centering}
 p{\celldim}
 <{\end{minipage}} 
 @{} }

\newcolumntype{Z}{ @{} >{\centering} p{\celldim} @{} }

\newenvironment{squarecells}[1]
  {\setlength\celldim{4.5em}%
   \settoheight\fontheight{A}%
   \setlength\extraheight{\celldim - \fontheight}%
   \setcounter{sqcolumns}{#1 - 1}%
   \begin{tabular}{|S|*{\value{sqcolumns}}{Z|}}\hline}
% squarecells tabular goes here
  {\end{tabular}}

\newcommand\nl{\tabularnewline\hline}

\begin{document}
  \Huge
  \begin{squarecells}{4}
    This is a long line & 3  & 2  & 13 \nl
    \cellcolor{red}5  & 10 & 11 & 8  \nl
    9  & 6  & 7  & 12 \nl
    4  & 15 & 14 & 1  \nl
  \end{squarecells}
\end{document}

谢谢

您在这里使用的表格有点不规范。由于您尝试将宽度设置为\celldim，因此您应该考虑到默认情况下，每列之间都有一些额外的间距，这些间距由长度控制\tabcolsep。因此，您的列实际上会像一样宽\celldim+\tabcolsep，但您的minipage宽度只有\celldim-。

将此添加到您的示例中意味着改变\tabcolsep您的内心environment

\newenvironment{squarecells}[1]
  {\setlength\celldim{4.5em}%
   \settoheight\fontheight{A}%
   \setlength\tabcolsep{0pt}
   \setlength\extraheight{\celldim - \fontheight}%
   \setcounter{sqcolumns}{#1 - 1}%
   \begin{tabular}{|S|*{\value{sqcolumns}}{Z|}}\hline}
% squarecells tabular goes here
  {\end{tabular}}

为了说明什么\tabcolsep，这里有一个简单的例子。

代码

\documentclass{article}
\usepackage{caption}

\begin{document}

\begin{table}[hbt]
  \centering
  \caption{\texttt{\textbackslash tabcolsep} unchanged }
\begin{tabular}{*{3}{|l}|}
\hline
  Some & random & stuff\\
    foo & bar & baz\\
\hline
\end{tabular}
\end{table}

\begin{table}[hbt]
  \setlength{\tabcolsep}{0pt}
  \centering
  \caption{\texttt{\textbackslash tabcolsep} set to 0 }
\begin{tabular}{*{3}{|l}|}
\hline
  Some & random & stuff\\
    foo & bar & baz\\
\hline
\end{tabular}
\end{table}

\end{document}
