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}

\usepackage[shadedcells]{ot-tableau}

\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}

\ShadingOn
\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 https://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 01:21
  • The problem is the dashed lines for unranked constraints can be drawn with tabu or arydshln, but tabu conflicts with colortbl, and arydshln conflicts with hhline. It was working in 2017.... – adam.baker May 19 '21 at 10:35

This was an error caused by an incompatibility of colortbl and tabu. The current version (soon to be available on CTAN, and also on GitHub now) shades cells correctly. There is a trade-off (because of obscure package dependencies and conflicts) in that the lines of the tableau are not as pretty; hopefully the package conflicts will be resolved in the future.
