Skip numeration figure and table caption

How to make a table and figure caption without any automatic numeration?

For example:

\begin{table}
    \begin{tabular}{ll}
    \textbf{Name} & \textbf{Description} \\
        Foo & bar \\
        Foo & bar
    \end{tabular}
    \caption{Ni开发者_JS百科ce Table a.I.3. Number of table passed in caption, so it don''t need any automatic numeration }
    \label{tab:table}
\end{table}

Use the caption package (http://www.ctan.org/tex-archive/macros/latex/contrib/caption/)

It defines the \caption* command for the table environment.
