[Tex/LaTex] About numbering of figures and tables in appendix {elsarticle.cls}

appendiceselsarticlefloatsnumbering

When I am using elsarticle.cls to write papers, I always meet the following problem. If I already have one picture (table) in main text and then I put another picture (table) in appendix, the numbering of the picture (table) in appendix is not Figure A.1 (Table A.1) but Figure A.2 (Table A.2).

I tried to modify the elsarticle.cls by adding

\renewcommand\appendix{\par
  \setcounter{section}{0}%
  \setcounter{subsection}{0}%
  \setcounter{equation}{0}
  \setcounter{figure}{0}
  \setcounter{table}{0}
  ....

But I failed, always encountering warnings and errors.

Here is the test code:

\documentclass[preprint,12pt]{elsarticle}
\begin{document}
\section{Test}
\begin{table}[h]
  \caption{Test}\label{Tab_1}
  \centering{}
  \begin{tabular}{c|c}
  \hline
  $E(\mathrm{Mpa})$ & $\nu$\\
  \hline
  $6.8\times10^4$ & 0.21\\
  \hline
  \end{tabular}
\end{table}
\appendix
\section{Test}
\begin{table}[h]
  \caption{Test}\label{Tab_2}
  \centering{}
  \begin{tabular}{c|c}
  \hline
  $E(\mathrm{Mpa})$ & $\nu$\\
  \hline
  $6.8\times10^4$ & 0.21\\
  \hline
  \end{tabular}
\end{table}
\end{document}

If we put picture we meet also the same problem.I do not know why this happen. Does mean that in appendix we can not put any table or figure? Can anyone help me out?

A copy and paste from elsarticle.cls

\makeatletter
\renewcommand\appendix{\par
  \setcounter{section}{0}%
  \setcounter{subsection}{0}%
  \setcounter{equation}{0}%
  \setcounter{table}{0}%------------ << add
  \setcounter{figure}{0}%----------- << add
  \gdef\theequation{\@Alph\c@section.\arabic{equation}}%
  \gdef\thefigure{\@Alph\c@section.\arabic{figure}}%
  \gdef\thetable{\@Alph\c@section.\arabic{table}}%
  \gdef\thesection{\appendixname\@Alph\c@section}%
  \@addtoreset{equation}{section}%
  \@addtoreset{table}{section}%----- << add
  \@addtoreset{figure}{section}%---- << add
}

[Tex/LaTex] How to put two tables in a table* element so that the tables appear side by side in a two column layout scientific paper

You should use the subfig package.

\begin{table*}
\subfloat[First caption]{\begin{tabular}{...}...\end{tabular}}
\subfloat[Second caption]{\begin{tabular}{...}...\end{tabular}}
\caption{Overall caption}
\end{table*}

This can be used in conjunction with the floatrow package. See the subfig documentation for an example that aligns captions using floatrow.

EDIT:
Your example has an extra \begin{table} that doesn't belong. It also has a blank line which causes TeX to start a new paragraph which is why one table appears on top of the other.

Here's a complete example where I've also cleaned up your tables following the guidelines given in the documentation to the booktabs package.

\documentclass[twocolumn]{article}
\usepackage{subfig}
\usepackage{booktabs}
\begin{document}
\begin{table*}
\subfloat[Before processing]{
\begin{tabular}{ccccc}
\toprule
Year & Month & Country & State & Impressions\\
\midrule
2007 & JAN & IN & TN & 3\\
2007 & JAN & IN & TN & 1\\
\bottomrule 
\end{tabular}
}%
\hfill
\subfloat[After processing]{
\begin{tabular}{ccccc}
\toprule 
Year & Month & Country & State & Impressions\\
\midrule 
2007 & JAN & IN & TN & 7\\
2007 & FEB & IN & KA & 13\\
\bottomrule 
\end{tabular}
}
\caption{overall}
\end{table*}
\end{document}

You have to repeat the resetting at every \section in the appendix.

\documentclass{article}
\usepackage[demo]{graphicx}
\usepackage[nofiglist,notablist]{endfloat}
\usepackage{etoolbox}

\begin{document}

\section{Section one}

The main figure is Figure~\ref{Figure-1}, and the main table is Table~\ref{Table-1}. Supplemental material 
includes Figure~\ref{Figure-A1} and Table~\ref{Table-A1} in the first appendix, and Figure~\ref{Figure-B1} 
and Figure~\ref{Figure-B2} in the second appendix.

\begin{figure}
    \includegraphics{fig1}
\caption{Figure one} \label{Figure-1}
\end{figure}

\begin{table}
    \begin{tabular}{ll}
        Row 1 & 1\\
        Row 2 & 2\\
        Row 3 & 3\\
        Row 4 & 4\\
    \end{tabular}
\caption{Table one}\label{Table-1}
