[Tex/LaTex] Change Section Label in Table of Contents and Section Title

Question

I need help with how sections created in the appendix are labeled in the table of contents and the section title itself.

As it sits now, I have each appendix as a section with a capitalized alpha character. Looking at the table of contents, I would like to change from "A Tables for Chapter One" to "Appendix A Tables for Chapter One." Likewise, I would like the title of the section (last page) to make the exact same change. Finally, I want the titles of each table and figure to remain as they are, i.e., without the word "Appendix."

Details: I am using the msuphddissertation class file, which is structured as a memoir. The contents of the class file are below the tex file with the example dissertation.

\documentclass{msuphddissertation}
\usepackage{subfig,chngcntr,titlesec}

\begin{document}

\TOC 
\LOT

\newpage
\addcontentsline{toc}{chapter}{APPENDICES}

\appendix

\counterwithin{table}{section}
\counterwithin{figure}{section}
\renewcommand\thesection{\Alph{section}}

\section{Tables for Chapter One}

\begin{table}[h!]
\center
\caption{Intestesting First Table}
\begin{tabular}{l*{4}{c}} \hline\hline
Var1 & 1.00 & 1.00 & 1.00 & 1.00\\
\hline\hline 
\end{tabular}
\end{table}

\end{document}

Answer 1

You can place the following code snippet immediately after your \appendix command:

\makeatletter
\addtocontents{toc}{%
  \protect\renewcommand\protect\cftsecpresnum{Appendix }% Prepend Appendix
  \protect\setlength\protect\cftsecnumwidth{6em}% Adjust width of section number in ToC
}
\renewcommand{\@seccntformat}[1]{Appendix~\csname the#1\endcsname \quad}
\makeatother

The first \addtocontents{toc}{...} stuff places the appropriate changes into the ToC file. More specifically, it prepends each section number with Appendix and provides an adjustment of the section number width (since it now contains the word Appendix as well). The second \@seccntformat prepends Appendix~ to the section number format (for all sectional units. Perhaps that's sufficient.
