I've been trying to include the diagram in the picture below in Latex, and I could achieve the result in the picture using the tabular environment. I was wondering, however, whether the same result can be achieved via Tikz. I've tried with no successful outcome. Thanks for any possible suggestions!
\documentclass{article}
\usepackage[T1]{fontenc} %font
\usepackage{arydshln}
\begin{document}
\begin{table}[]
\begin{tabular}{lllllll}
