I have created a table, inspired by this guide: http://www.tug.org/pracjourn/2007-1/mori/mori.pdf
Here is my result
\begin{table}[tp]%
\centering%
\begin{tabular}{cccccc}
\toprule%
&Table &Light [L] &$\zeta_0/2\pi$ [MHz] &Flux [1/s] &Dimensions [m] \\\toprule
&10 &3 &28.73 &asd &$(20\times 10)$ \\
&1 &3 &28.73 &asd &$(20\times 10)$ \\
&0 &3 &28.73 &asd &$(20\times 10)$ \\\bottomrule
\end{tabular}
\caption{Maximum load and nominal tension.}
\label{aggiungi}
\end{table}
I would like to hear what other people think of it. Personally I would like the distance beween the headlines and the lower toprule to be a little larger, but I'm not quite sure how to do that properly.
Any feedback and suggestions are greatly appreciated.


\midrulebetween the heading and the data rows, rather than a\toprule. – Yiannis Lazarides Dec 31 '12 at 13:15$20\times10$is metre or sqare metre. I'm guessing it's the latter? – cgnieder Dec 31 '12 at 13:16[$\unit{m}\times\unit{m}$](with an appropriate definition of\unitor even better usingsiunitxand its\siwhich is a good idea anyway if you need units more often) – cgnieder Dec 31 '12 at 13:48
