Question

以下是一张表格：

\begin{table}[h]
\begin{tabular}{llllllll}
\rowcolor[HTML]{EFEFEF} 
\textbf{foo}            & \textbf{bar}           & \textbf{foobar}        & \textbf{fsj}           & \textbf{jifd}          & \textbf{jifd}          & \textbf{jif}                                                          & \textbf{ifi}                                                          \\ \hline

现在我试图将\textbf{foo}（第一列的名称）更改为\neg B 但我收到以下错误：！缺少 $ 插入。$ l.55 }

Answer 1

正如评论中已经指出的那样，您需要 TeX 的数学模式才能使用\neg宏。即输入$\neg B$而不是仅仅输入\neg B。

表格的一个更根本的问题是代码是很多太复杂了。特别是，没有必要将每个单元格都包含在语句中\multicolumn{1}{...}{...}。这样做不仅效率极低，而且会使调试变得比需要的更加繁琐。在下面的代码中，你会发现没有一个 \multicolumn陈述。

\documentclass{book}
\usepackage[table]{xcolor}
% define a shortcut macro to change both cell and text color
\newcommand\combinedcolor{\cellcolor[HTML]{FFCCC9}\color[HTML]{3166FF}}
\begin{document}
\begin{table}[h]
\begin{tabular}{|l|l|l|l|l|l|l|l|}
\hline
\rowcolor[HTML]{EFEFEF}
$\neg B$ & \textbf{bar} & \textbf{foobar} & \textbf{fsj}  & 
\textbf{jifd} & \textbf{jifd} & \textbf{jif} & \textbf{ifi} \\ \hline
1 & 1 & 1 & 0 & 1 & 1 & \combinedcolor 1 & \combinedcolor 1 \\ \hline
1 & 1 & 0 & 0 & 0 & 1 & 0 & 1 \\ \hline
1 & 0 & 1 & 1 & 1 & 1 & \combinedcolor 1 & \combinedcolor 1 \\ \hline
1 & 0 & 0 & 1 & 1 & 1 & \combinedcolor 1 & \combinedcolor 1 \\ \hline
0 & 1 & 1 & 0 & 1 & 1 & \combinedcolor 1 & \combinedcolor 1 \\ \hline
0 & 1 & 0 & 0 & 0 & 1 & 0 & 0 \\ \hline
0 & 0 & 1 & 1 & 1 & 0 & 0 & 1 \\ \hline
0 & 0 & 0 & 1 & 1 & 0 & 0 & 0 \\ \hline
\end{tabular}
\end{table}
