I have main tables and appendix tables in my paper. I would like to number the appendix tables "A1", "A2", "A3", etc OR, at the very least, re-start the table numbering at 1 in the appendix. Any suggestions on how to do that?

Use \numberwithin from the amsmath package.
MWE:
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\section{Normal}
\begin{table}
\caption{Normal Table}
\end{table}
\appendix
\numberwithin{table}{section}
\section{First Appendix}
\begin{table}
\caption{Table in Appendix}
\end{table}
\end{document}
EDIT: Having seen This note on numberwithin outside the preamble (and this) here's an alternative version:
\documentclass{article}
\usepackage{chngcntr}
\begin{document}
\section{Normal}
\begin{table}
\caption{Normal Table}
\end{table}
\appendix
\counterwithin{table}{section}
\section{First Appendix}
\begin{table}
\caption{Table in Appendix}
\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.

The documentclass might provide more elegant options. But the following should do the trick, inserted where the appendix starts:
