[Tex/LaTex] Dotted line instead of \hline in table environment

Question

I am trying to get a dotted line in the table instead of \hline, but I can't get the output.

arydshln and dashrule packages are available to get the dashed line, but I can't find any packages to get a dotted line in table.

Is any package available for this style?

Answer 1

The package arydshln by Hiroshi Nakashima provides dashed lines, but they can be changed to look like dots, somehow, by reducing the dash length and increasing the gap a little bit (both default to 4pt)

Change the lengths \dashlinedash, \dashlinegap accordingly and \arrayrulewidth eventually.

\documentclass{book}

\usepackage{arydshln}

\setlength{\dashlinedash}{0.2pt}
\setlength{\dashlinegap}{4.5pt}
\setlength{\arrayrulewidth}{0.2pt}

\begin{document}
\begin{tabular}{ll}
\hline
& \\
This is a & nice table \\
& \\
\hdashline
& \\
\end{tabular}


% Another combination of values
\setlength\dashlinedash{0.2pt}
\setlength\dashlinegap{1.5pt}
\setlength\arrayrulewidth{0.3pt}

\begin{tabular}{ll}
\hline
This is yet & another nice table \\
\hdashline
\end{tabular}


\end{document}  

Edit: In a previous version I had\usepackage{array} -- this package is not needed, so I removed it from the code.
