Use lining figures in longtable

Question

@TH. has shown a great way to use lining figures in tables:

Palatino fonts and the number 713

Is there an equivalent for a longtable? Because neither @tabular nor @longtable gives me lining figures in the longtable. (Since I will only use longtables in the appendix it would be also okay (quick & dirty) to set lining figures globally at that point where I start the appendix)

mwe:

\documentclass{scrreprt}
\usepackage{longtable}
\usepackage{etoolbox}
\usepackage[sc,osf]{mathpazo}
\makeatletter
\preto\@tabular{\fontfamily{pplx}\selectfont}
\preto\@longtable{\fontfamily{pplx}\selectfont}
\makeatother

\begin{document}
text: 713

\begin{tabular}{c}
regular table\\
713
\end{tabular}

\begin{longtable}{c}
longtable\\
713 
\end{longtable}
\end{document}

Answer 1

In case of longtable macro \LT@array can be redefined:

\documentclass{scrreprt}
\usepackage{longtable}
\usepackage{etoolbox}
\usepackage[sc,osf]{mathpazo}
\makeatletter
\preto\@tabular{\fontfamily{pplx}\selectfont}
\preto\LT@array{\fontfamily{pplx}\selectfont}
\makeatother

\begin{document}
text: 713

\begin{tabular}{c}
regular table\\
713
\end{tabular}

\begin{longtable}{c}
longtable\\
713
\end{longtable}
\end{document}
