论文LaTeX制表

先加载：

\usepackage{threeparttable}

然后是代码：

\begin{center}
\begin{threeparttable}
\caption{The Skewing Angles ($\beta$) for $\fam0 Mu(H)+X_2$ and
   $\fam0 Mu(H)+HX$~\tnote{a}}
\begin{tabular}{rlcc}
\hline
&   & $\fam0 H(Mu)+F_2$ & $\fam0 H(Mu)+Cl_2$ \\
\hline
&$\beta$(H)  & $80.9^\circ\tnote{b}$ & $83.2^\circ$ \\
&$\beta$(Mu) & $86.7^\circ$ & $87.7^\circ$ \\
\hline
\end{tabular}
\begin{tablenotes}
\item[a] for the abstraction reaction, $\fam0 Mu+HX \rightarrow MuH+X$.
\item[b] 1 degree${} = \pi/180$ radians.
\end{tablenotes}
\end{threeparttable}

\end{center}

参考：threeparttable.sty中的example，原来还要先加载threeparttable，是不是所有的.sty文件用时都要加载？
