[Tex/LaTex] \ref shows the right label but jumps to the wrong \label

appendicescross-referencinghyperrefsubfloats

in this MWE you can see/explore (hopefully, as it does not work for me) that \ref{tab:2} produces the right label but if you click on it, it will lead you to the \label{tab:1}.
\usepackage{appendix} and \begin{appendix} ... \end{appendix} doesn't helped and as I assume I'm using the \label at the right position.

EDIT: The solution putting the \numbering behind the hyperref worked well(!), but another error occured in combination with subfigures. The label does not fit anymore, if the \numbering is placed before the include of the subfigure package. I´ve heard that hyperref should be the last included package for some reasons, but as solution for this error: Can I just place the \usepackage{subfigure} after hyperref and \numbering?

Best Answer

hyperref supports \numberwithin, but only if it awares of it. Therefore, \numberwithin should be used after package hyperref.

Further remarks:

  • Option allcolors simplifies the setting of the colors to one color with option colorlinks.

  • Package hyperref detects driver pdftex automatically, it does not need to be set explicitly.

  • KOMAScript option captions=tableheading fixes the skip settings around table captions, which are used above the table. Thus, the empty line hack can be removed.
