Letex画复杂表格的方法

帮朋友画了一个表格，相对复杂，把代码记载于此，以后不用自己写。

\begin{table}[!htb]
\newcommand{\tabincell}[2]{\begin{tabular}{@{}#1@{}}#2\end{tabular}}
\caption{Comparison of Computation overhead}
\label{table:Comparison of Computation}\centering
\vspace{10pt}
\begin{tabular}{|c|ccccccc|}
\hline
   \multirow{3}{1.2cm}{Year}& \multicolumn{7}{c|}{PM10} \\ \cline{2-8}
   & \multirow{2}{1.2cm}{Peal value}&\multicolumn{2}{c}{Tran vue }&\multicolumn{2}{c}{BGM(1,1)}&\multicolumn{2}{c|}{IOBGM(1,1)} \\ \cline{3-8}
   & & F V & R E & F V &\tabincell{c}{R\\V }& F V & R E \\ \hline
   2011 & 1 & 2& 3& 4& 5& 6& 7 \\
   2012 & 1 & 2& 3& 4& 5& 6& 7\\ \hline

\end{tabular}
\end{table}
