問題
multicol嘿，我花了大約 3 個小時試圖用LaTeX解決這個問題。希望它能幫助一些人：LaTeX 中的陣列截斷
正如您所看到的，我在環境中的數組在環境中看起來很好的環境中\align*被切斷：multicol\align*align*環境中的數組
這是我的程式碼：
\begin{align*}...\end{align*}沒有切斷：

解決方案
如果你編譯的 LaTeX 解決方案是將 long 分成\begin{align*}...\end{align*}幾個“\begin{align*}...\end{align*}”，那麼你會得到類似的東西：
\begin{multicol}{2}
...
\begin{align*}...\end{align*}
\begin{align*}...\end{align*}
\begin{align*}...\end{align*}
...
\end{multicol}
所以，正確的程式碼：
\begin{multicol*}{2}
