Starting from my question Does a symbol for glasses exist? and from the best @Milo's answer, I have created this MWE, using the macro \advice,
\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{tikz}
\usepackage{colortbl}
\definecolor{ocre}{RGB}{243,102,25}
\newcommand{\glasses}{\resizebox{3em}{!}{%
\tikz{\draw(0,0) coordinate (Origin) --++(0.2,0) coordinate (endL) arc (180:0:0.05)--++(0.2,0) coordinate (endR) --++(45:0.25) arc (180-45:0:0.08) (endR) arc (0:-180:0.1) (endL) arc (0:-180:0.1) (Origin)--++(45:0.25) arc (180-45:0:0.08);
}}}
\newcommand{\advice}{\begin{table}[ht]
\centering
{\renewcommand{\arraystretch}{1.8}
\begin{tabular}{c!{\color{white}\vrule width 1pt}c}
\rowcolor{olive!20}
\textcolor{ocre}{\glasses\, \textbf{\textsc{\large Attenzione:}}} & \cellcolor{gray!15} Long Long empty cell with a break \\
\end{tabular}}
\end{table}}
\begin{document}
\advice
\end{document}
to have this output:
How do I create a visible break effect for the second column colored gray? For the second column coloured in grey I would like to have a roughness effect like the image, coarse, shown in the best figure created from @David Carlisle in his comment:
