Latex multicolumn problems

Question

I am trying to build a table in latex where five columns have a common title centered above the columns. But the generated table does not appear as expected. (the common title is left justified instead of centered above the columns)

The code looks like

\documentclass{article}

\begin{document}

\begin{table}
\centering
\begin{tabular}{|l|c|c|c|r|}
\multicolumn{5}{c}{Hydrotalcite} \\
\hline
kalhsdfsa & 1 asdf asf asfa &7as dfas fasdf as0 & 003  \\
kalhsdfsa & 1 asdf asf asfa &7as dfas fasdf as0 & 003  \\
kalhsdfsa & 1 asdf asf asfa &7as dfas fasdf as0 & 003 
\end{tabular}
\caption{lala}
\label{tabTableRefereaSDasdnce}
\end{table}

\end{document}

And I'm running miktex 2.8 on Windows XP

Answer 1

your multicolumn amount is one too high

change to \multicolumn{4}{c}{Hydrotalcite} \\\hline

(in stead of \multicolumn{5}{c}{Hydrotalcite} \\\hline)

or actually add the fifth column ;-)
