自定义表格列

Question

尝试弄清楚如何在 overleaf 中制作这些表格。顶部的拆分列是造成我麻烦的原因。

Answer 1

\sffamily
\begin{tabular}{|c|c|c|}
\hline
\multicolumn{2}{|c|}{\textbf{INPUT}} & \textbf{OUTPUT} \\ \hline
A                 & B                & A NAND B        \\ \hline
0                 & 0                & 1               \\ \hline
0                 & 1                & 1               \\ \hline
1                 & 0                & 1               \\ \hline
1                 & 1                & 0               \\ \hline
\end{tabular}
\quad %
\begin{tabular}{|c|c|c|}
\hline
\multicolumn{2}{|c|}{\textbf{INPUT}} & \textbf{OUTPUT} \\ \hline
A                 & B                & A AND B         \\ \hline
0                 & 0                & 0               \\ \hline
0                 & 1                & 0               \\ \hline
1                 & 0                & 0               \\ \hline
1                 & 1                & 1               \\ \hline
\end{tabular}

我认为这是你要找的桌子（没有任何旋转）

\documentclass[12pt,a4paper]{article}

\usepackage{array}

\begin{document}    
\sffamily
\renewcommand{\arraystretch}{2} % adjust to expand the cells vertically
\begin{tabular}{|c|c|c|c|}
    \hline
    \multicolumn{2}{|c|}{\bfseries INPUT} & \multicolumn{2}{c|}{\bfseries OUTPUT} \\ \hline
    A & B   & A NAND B  & A AND B  \\ \hline
    0 & 0   & 1         & 0         \\ \hline
    0 & 1   & 1         & 0         \\ \hline
    1 & 0   & 1         & 0         \\ \hline
    1 & 1   & 0         & 1         \\ \hline
\end{tabular}   
    
\end{document}

Answer 3

如果您不想旋转，只需用于\multicolumn拆分列即可。

\documentclass{article}

\begin{document}
    \begin{table}[]
        \centering
        \begin{tabular}{|c|c|c|}
            \hline
            \multicolumn{2}{|c|}{INPUT} & OUTPUT  \\ \hline
            A            & B            & A AND B \\ \hline
            0            & 0            & 1       \\ \hline
            0            & 1            & 1       \\ \hline
            1            & 0            & 1       \\ \hline
            1            & 1            & 0       \\ \hline
        \end{tabular}
    \end{table}
\end{document}
