ctable indentation

Hi,

I've started  using ctable for typesetting tables
(http://www.ctan.org/tex-archive/help/Catalogue/entries/ctable.html),
and the main macro has the structure:

\ctable[options]{coldefs}{foottable}{table lines}

and would like to indent it in AUCTeX almost like an environment, e.g.:

\ctable[caption = table title,
        label   = tab:1,
        ...]
       {lll}
       {\tnote{first note}
        \tnore[b]{second note}
        ...}
       {column 1 & column 2 & column 3 \\
        ...      & ...      & ... }

Otherwise it's very difficul to read. What variable or function should I
look at to specify something like this in AUCTeX?
