Latex 中表格添加标注的三种方法
1、\begin{table}
\tbl{Radio-band beaming model parameters for\\ {FSRQs and BL Lacs.}}
{\begin{tabular}[l]{@{}lcccccc}
\toprule
Class$^{\rm a}$ & $\gamma _1$ & $\gamma _2$$^{\rm b}$
& $\langle \gamma \rangle$
& $G$ & $|{\bm f}|$ & $\theta _{c}$ \\
\colrule
BL Lacs &5 & 36 & 7 & $-4.0$ & $1.0\times 10^{-2}$ & 10$^\circ$ \\
FSRQs & 5 & 40 & 11 & $-2.3$ & $0.5\times 10^{-2}$ & 14$^\circ$ \\
\botrule
\end{tabular}}
\tabnote{$^{\rm a}$This footnote shows what footnote symbols to use.}
\tabnote{$^{\rm b}$This footnote shows the text turning over when a long footnote is added.}
\label{symbols}
\end{table}

1、注意使用\usepackage{footnote}
% \begin{table}[!h]
\begin{table}
\centering
\caption{Optimal results for two different load cases}
\label{Tab:03}
\begin{tabular}{ccccc}
\hline
% after \\: \hline or \cline{col1-col2} \cline{col3-col4} ...
Cases & Component shapes & Initial layout & Optimized layout & Objective function\\
\hline

& \\
\cline{1-5}
\hline
\end{tabular}
\footnotesize{$^a$ The smallest spatial unit is county}\\
\end{table}

1、使用
\begin{savenotes}
\footnote{This is the first footnote.}
……
\end{savenotes}
具体代码如下
\begin{savenotes}
