I have having some trouble setting a table.

I would like it to look something like this (sorry,
you will need a monospaced font to see
it correctly ...). It could have vertical lines completing
the boxes on the ends, and indeed that is what I tried to
do ... but my attempt, below, fails. Could someone point
me in the correct direction please? I would very much
appreciate the help.

-----------------------------------------
                    CIE coordinates
              --------------------------
Observer         x        y          z
-----------------------------------------
ABC            0.0      0.1        0.9
DEF            0.3      0.3        0.3
-----------------------------------------



I have tried the ...

\begin{table}[h]
  \center{
  \begin{tabular}{|lp{2cm}|cp{2cm}|cp{2cm}|cp{2cm}|} \hline
     & \multicolumn{3}{c}{\emph{CIE co{\"o}rdinates}} \\
    \emph{Observer} & $x$   & $y$ & $z$ \\ \hline
    JAM & $0.452$ & $0.486$ & $0.062$ \\
    MCM & $0.450$ & $0.491$ & $0.059$ \\
    JR  & $0.426$ & $0.506$ & $0.068$ \\ \hline
  \end{tabular}
  }
  \caption{CIE co{\"o}rdinates for all observers.}
  \label{tab1}
\end{table}

but as you will see, it does not work.

Cheers,
