除了使用multirow的方式(比较麻烦),更好地办法是用下面的语句,可以使得一个单元格中显示多行,再配合其它格式语句,就能使得表格非常美观。
\newcommand{\tabincell}[2]{\begin{tabular}{@{}#[email protected]{}}#2\end{tabular}}
下面一个比较综合的例子:
\begin{table*}[htbp]
\centering
\newcommand{\tabincell}[2]{\begin{tabular}{@{}#[email protected]{}}#2\end{tabular}}
\caption{XXXXXXX}
\begin{tabular}{|m{0.5cm}<{\centering}|m{2.5cm}<{\centering}|m{1.5cm}<{\centering}|m{1.5cm}<{\centering}|m{1.5cm}<{\centering}|m{1.5cm}<{\centering}|m{1.5cm}<{\centering}|}
\hline
\multicolumn{2}{|m{3cm}<{\centering}|}{Test instance}&
Number of the decision variables &
The decision space &
Number of the linear equations &
Number of the nonlinear equations &
Number of the optimal solutions\\
\hline
F1 &
\tabincell{l}{equ1 \\ equ2} &

\end{table*}
