\end{document}

provides the table shown in the picture. As you could see, the first column is not well aligned with the others. I cannot figure how to fix it. Any suggestions?

A solution wirh the \compress command which makes latex believe that entering a cell in the relevant columns, a new minipage is starting:

\documentclass[a4paper]{article}

Edit: To remove the vertical space at the bottom of cells with lists, you may add a negative vertical space ain leaving the corresponding cells , replacing the table preamble with the following!

\begin{tabular}{l >{\compress}p{5.0cm}<{\vspace* {-\baselineskip}}>{\compress}p{5.0cm}<{\vspace* {-\baselineskip}}c}
