• please, let code be complete but small document (called minimal working example: mwe) beginning with \documentclass{...} and ended by \end{document}. in document preamble let be only for your table relevant packages and your \newcommands. Mar 23 '18 at 23:55

\setlength{\rightcol}{\textwidth-\leftcol}
