@[ViXbob](/space/show?uid=50971) 洛谷的LaTeX貌似不支持\mbox

@[Iowa_BattleShip](/space/show?uid=60181) 那您知道该怎么打吗？

@[ViXbob](/space/show?uid=50971) 您说下要实现什么样的功能

@[Iowa_BattleShip](/space/show?uid=60181) 大概就是我发的那个链接里的效果

@[ViXbob](/space/show?uid=50971) 这不是markdown么……

@[Iowa_BattleShip](/space/show?uid=60181) 中间插入的那个就是LaTeX啊

@[ViXbob](/space/show?uid=50971)
他中间的LaTeX在洛谷是这么打的
```cpp
$E=mc^2$
```
效果：$E=mc^2$
您说的大括号是这么打的
```cpp
$\begin{cases}a\\b\\c\end{cases}$
以双右斜杠'\\'来换行
```
效果：$\begin{cases}a\\b\\c\end{cases}$
