With ctable, you cannot have any blank lines within the table's definition, as
compared to a normal tabular environment. This is because ctable is a command,
as opposed to an environment. That is, you use \ctable[...]{...} as opposed to
\begin{tabular} ... \end{tabular}.
I recall coming across that issue when implementing my own reporting tools for
use in Sweave, where I default to the use of ctable, as I prefer the look. One
approach instead of removing the blank lines, is to just comment them out (eg.
using a '%' character).
I am cc'ing Frank here, in case he is not aware of this, albeit I presume that
he is and that this behavior is a buglet.
