3. 定界符 | 分隔符
建议使用\left S1和\right S2来匹配定界符S1和S2内容的高度(S1和S2表示两个符号对),如: \left| expression \right| ->

r
e

\left| expression \right|
∣expression∣ \left\{ expression \right\} ->

\left\{ expression \right\}

\tan(at-n\pi)
tan(at−nπ) 错误:tan(at-n\pi) −>

10. 矩阵 | 阵列环境及其实例
最简单的格式:\begin{array}{cols} row1 \\ row2 \\ . . . rowm \end{array}
其中cols包括每一列的一个字符l, r, c (垂直线 | 为可选插入字符),rowj包括字符&共(n - 1)个,用于分隔行中的n个元素。
例如: $\left( \begin{array}{cc} 2\tau & 7\phi-\frac5{12} \\ 3\psi & \frac{\pi}8 \end{array} \right)$

其余KaTex语法无法显示的就不写了,反正这部分也几乎不会用到。
参考美国莱斯大学计算与应用数学学院(Rice CAAM)发表的文档,并做了部分错误修正。 如有错漏请不吝指正。
这些符号比较多,就不写使用例子了,更多LaTex | Markdown语法我会写在另起文章。
