I'm trying to meld tcolorbox with an array in order to nicely identify exercices, with corresponding grade and difficulty level. I cannot get rid of the right angles (see pic below). I'd like to have the box rule "above" the array, in order to mask the rectangular cell and their right angles.
Additionnally, if someone could give me any clue for the best way to vertically center the text with respect to its actual height (with no space reservation in case of some letters could extend below the base line)...
I'm using LuaLaTeX. Here is the code I wrote to get the result show in the pic.
\documentclass[12pt, english, french]{article}
\usepackage{babel}
\frenchsetup{og=«, fg=»}
\usepackage{fontspec}
\setmainfont{Erewhon}
\setsansfont[Scale=MatchLowercase]{Cabin}
\setmonofont[Scale=MatchLowercase,HyphenChar=None]{Inconsolatazi4}
\usepackage[most]{tcolorbox}
\usepackage{array, colortbl, fourier-otf, fontawesome, multicol, multirow, xcolor}
\begin{document}
\tcbox[left=0ex, right=0ex, top=0ex, bottom=0ex, boxsep=0pt, boxrule=2pt]
{\begin{tabular}{p{3cm}m{1.5cm}}
\multirow{2}{*}{Exercice 17} & \cellcolor{cyan}\textcolor{white}{1\iere} \\
& \cellcolor{black!50!white}\textcolor{white}{\scriptsize \faStar\faStar\faStarO}
\end{tabular}}
\end{document}
Thanks & regards !
