# Right justify columns in border matrix

I would like to right justify the columns in a border matrix. Is this possible? Default seems to be centre

 \documentclass{article}
\begin{document}

$\bordermatrix{~ & 5 & 6\cr 5 & 1 & 0 \cr 6 & 0 & -1 \cr}$
\end{document}


I don't know if it is possible with bordermatrix, but it is with kbordermatrix by issuing

\kbalignrighttrue


The following lines are to simulate the behavior of bordermatrix

\renewcommand{\kbldelim}{(}
\renewcommand{\kbrdelim}{)}
\renewcommand{\kbrowstyle}{\displaystyle}
\renewcommand{\kbcolstyle}{\displaystyle}


MWE:

\documentclass{article}

\usepackage{kbordermatrix}
\kbalignrighttrue
\renewcommand{\kbldelim}{(}
\renewcommand{\kbrdelim}{)}
\renewcommand{\kbrowstyle}{\displaystyle}
\renewcommand{\kbcolstyle}{\displaystyle}

\begin{document}

$\kbordermatrix{~ & 5 & 6\cr 5 & 1 & 0 \cr 6 & 0 & -1 \cr}$

\end{document}


Output
