Article appendix figures and tables caption and references in the form "Appendix Figure X" and “Appendix Table X”

Question

Much like is done with section headers using the appendix package here, I would like appendix tables and figures to have distinct captions and references. That is, for tables and figure that I move to the appendix, the labels in front of the captions should be "Appendix Table 1: ...", "Appendix Figure 1: ...", etc.

In addition, I like the references for such exhibits to include the word "Appendix", as in "As is seen in Appendix Table 1, ..." etc. Of course, this can be done using a separate command for appendix references, but they question is whether there is a fix so that it happens automatically for any exhibit once it is moved to the appendix.

Answer 1

You did not provide an example, but here is what I think you are trying to do

From etoolbox package, use the commands

\AtBeginEnvironment{subappendices}{\renewcommand{\figurename}{}
    \renewcommand{\thefigure}{\textbf{Appendix Figure \arabic{figure}}}
                                }
\AtBeginEnvironment{subappendices}{\renewcommand{\tablename}{}
    \renewcommand{\thetable}{\textbf{Appendix Table \arabic{table}}}
                                }

This renews the labels only for the appendices. Of course, you must check if your class automatically resets the counter of appendices once you have opened subappendices environment

\documentclass[11pt,a4paper,oneside]{book}

\usepackage{etoolbox}

\usepackage{appendix}
\AtBeginEnvironment{subappendices}{\renewcommand{\figurename}{}
    \renewcommand{\thefigure}{\textbf{Appendix Figure \arabic{figure}}}
                            }
\AtBeginEnvironment{subappendices}{\renewcommand{\tablename}{}
    \renewcommand{\thetable}{\textbf{Appendix Table \arabic{table}}}
                            }

\usepackage{graphicx}

\newcommand{\sampleEquationFloats}{

\begin{figure}
    \includegraphics[]{example-image-a}
    \caption{My Caption}
\end{figure}

\begin{equation}
    E = m c^{2}
\end{equation}

\begin{table}
    \caption{Table Caption}
    \centering
    \begin{tabular}{|c |c|}
        \hline
        Column & Column
        \\
        \hline
    \end{tabular}
\end{table}

}
