首先使用包usepackage{multirow}

命令符：

begin{table}[!hbp]

begin{tabular}{|c|c|c|c|c|}

hline

hline

lable 1-1 & label 1-2 & label 1-3& label 1 -4 & label 1-5 \

hline

label 2-1 & label 2-2 & label 3-3& label 4-4 & label 5-5 \

hline

multirow{2}{*}{Multi-Row} &multicolumn{2}{|c|}{Multi-Column} &multicolumn{2}{|c|}{multirow{2}{*}{Multi-Row and Col}} \

cline{2-3}

& column-1 & column-2 &multicolumn{2}{|c|}{}\

hline

end{tabular}

caption{My first table}

end{table}

end{document}

2，输入连等式

begin{align*}

  m'=[[<c,s>]_q]_t&=[[{c^T}cdot s]_q]_t  \

               &=[[(overline{m}^T+r^T)cdot s]_q]_t\

                &=[m+tr^Te]_t=m

end{align*}

数学符号连交的输入

$\bigcup \limits_{i=1}$
