if-else 符号的对齐

Question

我有三个连续的 if-else 条件符号。我想将它们的括号对齐在一起，但做不到。

    \begin{equation*}
\begin{rcases}
  \texttt{Chapter 1} \\
  \texttt{Chapter 2}\\
  \texttt{Chapter 3}
\end{rcases}
\text{Vector algebra, Simple Differentiation and Integration}
\end{equation*}
\begin{equation*}
\begin{rcases}
  \texttt{Chapter 4} \\
  \texttt{Chapter 5}\\
  \texttt{Chapter 6}
\end{rcases}
\text{Vector Calculus}
\end{equation*}
\begin{equation*}
\begin{rcases}
  \texttt{Chapter 7} \\
\end{rcases}
\text{Vector calculus and Tensor algebra}
\end{equation*}

Answer 1

我猜你想要一个NiceTabular（参见的手册nicematrix）。

\documentclass{article}
\usepackage{nicematrix}

\begin{document}

\begin{NiceTabular}{ll}
  Chapter 1 & \Block{3-1}{Vector algebra, Simple Differentiation and Integration} \\
  Chapter 2 & \\
  Chapter 3 & \\
  \\
  Chapter 4 & \Block{3-1}{Vector calculus} \\
  Chapter 5 & \\
  Chapter 6 & \\
  \\
  Chapter 7 & Vector calculus and Tensor algebra \\
\CodeAfter
  \SubMatrix.{1-1}{3-1}\}
  \SubMatrix.{5-1}{7-1}\}
  \SubMatrix.{9-1}{9-1}\}
\end{NiceTabular}

\end{document}
