Question

如何使用大花括号将左侧表格的各行组合在一起？

\documentclass{article}

\begin{document}
\begin{center}
\textbf{$n=3$}
\begin{tabular}{ |c|c| } 
 \hline
 Partition of $n$ & Conjugacy Class Representative\\
 \hline
 $1+1+1$ & $(1)$\\
 \hline
 $1+2$ & $(12)$\\
 \hline
 $3$ & $(123)$\\
 \hline
\end{tabular}
\end{center}
\begin{center}
\textbf{$n=4$}
\begin{tabular}{ |c|c| } 
 \hline
 Partition of $n$ & Conjugacy Class Representative\\
 \hline
 $1+1+1+1$ & $(1)$\\
 \hline
 $1+1+2$ & $(12)$\\
 \hline
 $2+2$ & $(12)(34)$\\
 \hline
 $1+3$ & $(123)$\\
 \hline
 $4$ & $(1234)$\\
 \hline
\end{tabular}
\end{center}
\end{document}

Answer 1

您可以使用array环境tabular并将每个array环境包裹在\left\{ ... \right.包装器中。

\documentclass{article}
\usepackage{array,amsmath}
\begin{document}

\[
n=3 
\left\{ \begin{array}{ |c|c| } 
 \hline
 \text{Partition of $n$} & \text{Conjugacy Class Representative}\\
 \hline
 1+1+1 & (1)\\
 \hline
 1+2 & (12)\\
 \hline
 3 & (123)\\
 \hline
\end{array}\right.
\]

\[
n=4 
\left\{ \begin{array}{ |c|c| } 
 \hline
 \text{Partition of $n$} & \text{Conjugacy Class Representative}\\
 \hline
 1+1+1+1 & (1)\\
 \hline
 1+1+2 & (12)\\
 \hline
 2+2 & (12)(34)\\
 \hline
 1+3 & (123)\\
 \hline
 4 & (1234)\\
 \hline
\end{array} \right.
\]
\end{document}
