# Shaded cells option in ot-tableau

I am using the package ot-tableau to make OT tableaux and there is an option for shaded cells. In the package documentation, the cells appear as shaded but when I use the exact same code from the documentation the cells don't appear shaded.

\documentclass{article}
\usepackage[utf8]{inputenc}

\begin{document}

\begin{tableau}{c|c}
\inp{\ips{ba}} \const{*VcdObs} \const*{\textsc{Ident-IO}-[nas]}
\cand{ba} \vio{*!} \vio{}
\cand[\HandRight]{pa} \vio{} \vio{*}
\end{tableau}

\begin{tableau}{c|c}
\inp{\ips{ba}} \const{*VcdObs} \const*{\textsc{Ident-IO}-[nas]}
\cand{ba} \vio{*!} \vio{}
\cand[\HandRight]{pa} \vio{} \vio{*}
\end{tableau}

\end{document}


• Welcome! See github.com/tabu-issues-for-future-maintainer/tabu. I recommend contacting ot-tableau's author with a reference to the GitHub page. Compiling the documentation also omits shading. I don't know this is a tabu issue, but the state of that package makes it very likely. If it is a tabu issue, ot-tableau's author could report it, but no package which depends on tabu can be recommended at present. Unfortunately, that means you'd be well advised to look for an alternative to ot-tableau unless the author plans to migrate from tabu. – cfr Oct 18 '19 at 1:21
