(Solved, New) Parenthesis while using subfig and autoref

Question

MWE first.

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{hyperref}
\usepackage[subrefformat=simple,labelformat=simple]{subfig}

%\newcommand{\subfigureautorefname}{\figureautorefname}
%\renewcommand\thesubfigure{(\alph{subfigure})}

\begin{document}
\begin{figure}
\subfloat[]{\label{a}\qquad}
\caption{}
\end{figure}
\begin{tabular}{|c|c|}
\hline
&Result\\\hline
ref&\ref{a}\\\hline
subref&\subref{a}\\\hline
autoref&\autoref{a}\\\hline
subref*&\subref*{a}\\\hline
\end{tabular}
\end{document}

I use package subfig to create subfigures and I want to use both \subref in captions and \autoref in the context.

My desired output of \subref and \autoref are (a) and Figure 1(a) respectively, but I'm not able to achieve them at the same time. I have tried different options for subfig and the solution here(where this question title came from). I also tried to create a new command but failed because I know little about macro or something like that.

Edit: Thanks for @Mico 's solution using package subcaption! I prefer to stick to subfig because it's exhausting to edit all floats in my document.

So I didn't check the subfig manual carefully enough. There are 3 options for typesetting subfloat labels. labelformat sets the label displayed under each subfloat. listofformat sets the output of \subref. subrefformat sets the output of \subref*.

In my case, I only need to add listofformat=subsimple to get rid of the extra pair of parens in \subref, then I could use \renewcommand\thesubfigure{(\alph{subfigure})} to add the parens to \autoref. Full solution below. I didn't notice listofformat because its name can't seem to do anything, compared to subrefformat.

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{hyperref}
\usepackage[listofformat=subsimple,labelformat=simple]{subfig}

\newcommand{\subfigureautorefname}{\figureautorefname}
\renewcommand\thesubfigure{(\alph{subfigure})}

\begin{document}
\begin{figure}
\subfloat[]{\label{a}\qquad}
\caption{}
\end{figure}
\begin{tabular}{|c|c|}
\hline
&Result\\\hline
subref&\subref{a}\\\hline
autoref&\autoref{a}\\\hline
\end{tabular}
\end{document}

Answer 1

Here's a subcaption-based solution, which works with both \autoref and \cref (provided by the cleveref package).

\documentclass{article}
\usepackage[demo]{graphicx} % remove 'demo' option in real document
\usepackage[utf8]{inputenc}

\usepackage{subcaption}
\renewcommand\thesubfigure{(\alph{subfigure})}
\captionsetup[subfigure]{labelformat=simple}

\usepackage[colorlinks]{hyperref}
\usepackage[nameinlink]{cleveref}

\begin{document}

\begin{figure}
\centering
\subcaptionbox{First subfigure\label{a}}{\includegraphics[width=0.25\textwidth]{figa}}%
\qquad
\subcaptionbox{Second subfigure\label{b}}{\includegraphics[width=0.25\textwidth]{figa}}
\caption{A figure with two subfigures}
\end{figure}

\begin{tabular}{ll}
\textbackslash ref    &\ref{a}    \\
\textbackslash subref &\subref{a} \\
\textbackslash subref*&\subref*{a}\\
\textbackslash autoref&\autoref{a}\\
\textbackslash Cref   &\Cref{a}
\end{tabular}
\end{document}
