# Adding a dashed horizontal line in a csv table

I am new to Latex and I am trying to generate a table for a document. I would like to have a horizontal line after the head and horizontal dashed lines between each entry. This is visible on the horrible image.

I have tried to find how to do it online but my attempt has failed, and this is why I am asking you help.

\documentclass{article}
\usepackage{csvsimple}
\begin{document}
\begin{tabular}{|p{5cm}|c | c | c | c | c |}\hline%
\bfseries Variables & \bfseries Obs. & \bfseries Mean & \bfseries Std.~Dev. & \bfseries Min & \bfseries Max
{\\\ \Variables & \Observations & \Mean & \StdDev & \Min & \Max}%
\\\hline
\end{tabular}
\end{document}

• Welcome to TeX SX! The code cannot be compiled. How do you define \Variables, \Observations and so on? – Bernard Nov 6 '16 at 13:11

The arydshln package provides a \hdashline command for adding dashed lines:
