Aligning the tops of two tabularx environments

Question

I have used the following to place two tabularx environments next to each other

\begin{table}
\begin{center}
\begin{tabularx}{190pt}{l}
\toprule
... Content ...
\bottomrule
\end{tabularx}
\quad
\begin{tabularx}{190pt}{l}
\toprule
... Content ...
\bottomrule
\end{tabularx}
\end{center}
\end{table}

How would I further align the tops of the two tabularx environments?

Answer 1

Use the [t] argument on each of the tabularx.

Answer 2

Use minipages:

\documentclass{book}
\usepackage{tabularx,booktabs}
\begin{document}
\begin{minipage}[l]{200pt}{%
\centering
\begin{tabularx}{190pt}{X}
\toprule
... Content ...\\\midrule
... Content ...\\
\bottomrule
\end{tabularx}}
\end{minipage}
\hfill
\begin{minipage}[r]{200pt}{%
\centering
\begin{tabularx}{190pt}{X}
\toprule
... Content ...\\\midrule
... Content ...\\
\bottomrule
\end{tabularx}}
\end{minipage}
%
\end{document}
