I am looking for a two-column solution: The left column contains one table, the right column several tables. I was thinking of using parboxes as follows:
\parbox[t]{2cm}{\vspace{0pt}
\begin{tabular}{ccc}
x & x & x\\
x & x & x\\
x & x & x\\
x & x & x\\
x & x & x
\end{tabular}}
\hfill
\parbox[t]{2cm}{\vspace{0pt}
\begin{tabular}{ccc}
x & x & x\\
x & x & x
\end{tabular}\\[1em]
\begin{tabular}{ccc}
x & x & x
\end{tabular}}
But this creates a nasty space between whatever comes before the two columns. Without \vspace{0pt}, the two first tables in both columns are not top-aligned. I am looking for a top-aligned solution without the extra space before the two columns.
