Unexpected table/figure reference

Question

Code

Consider the follwing example:

\documentclass[danish]{article}
\usepackage{polyglossia}
\setdefaultlanguage{danish}
\usepackage[demo]{graphicx}
\usepackage{booktabs}
\usepackage{floatrow}
\newfloatcommand{capbtabbox}{table}[][\FBwidth]
\usepackage{caption,subcaption}
\usepackage{siunitx}
\usepackage{hyperref}
\begin{document}
\begin{figure}
\begin{floatrow}
  \ffigbox{
    \includegraphics[width = 0.2\textwidth]{image1}%
  }{
    \caption{Figure caption.}
    \label{fig:1}
  }
  \capbtabbox{%
    \begin{tabular}{
      l
      S[table-format = 2]
    }
     \toprule
      Næring~[\qty{1}{\g}] & {Energi~(\unit{\kJ})} \
     \midrule
      Protein              & 17 \[0.5ex]
      Fedtstof             & 38 \[0.5ex]
      Kulhydrat            & 17 \[0.5ex]
      Alkohol              & 30 \
     \bottomrule
    \end{tabular}
  }{
    \caption{Table caption.}
    \label{tbl:1}
  }
\end{floatrow}
\end{figure}
\autoref{tbl:1}
\end{document}

Question

How to I make a reference to the table and not to the figure?

Answer 1

First, \autoref does not use \@currentlabelname but rather uses \@currentHref to get the counter name. However, every caption in a figure uses the same \@currentHref, which is set at the top of the figure.

One can use \capstart from the hypcap package to add another \@currentHref with the desired \@captype (table).

I didn't use floatrow mostly to make sure it wasn't the source of the problem (which it often is).

\documentclass[danish]{article}
\usepackage{polyglossia}
\setdefaultlanguage{danish}

\usepackage{caption,subcaption}
\usepackage{siunitx}
\usepackage{hyperref}
\usepackage{hypcap}
\makeatletter
\newcommand{\setcaptype}[1]% #1 = figure or table
  {\def@captype{#1}}
\newcommand{\setlabelname}[1]{\def@currentlabelname{#1}\ignorespaces}
\makeatother
\begin{document}
\setcounter{table}{1}
\begin{figure}

    \centering
    \includegraphics[width = 0.2\textwidth]{image1}%
    \caption{Figure caption.}
    \label{fig:1}
\end{minipage}\hfill
\begin{minipage}[b]{\dimexpr 0.5\textwidth-0.5\columnsep}
  \setcaptype{table}\capstart
    \centering
    \begin{tabular}[b]{
      l
      S[table-format = 2]
    }
     \toprule
      Næring~[\qty{1}{\g}] & {Energi~(\unit{\kJ})} \
     \midrule
      Protein              & 17 \[0.5ex]

     \bottomrule
    \end{tabular}
    \caption{Table caption.}
    \setlabelname{notused}

\end{figure}
\autoref{tbl:1}
