possible to adjust column widths of api listings?

[Philip Kovacs <kovacsp3 comcast net>]

I just installed gtk-doc 1.6 and have a quick question.

Many of my function names are quite long and the tabular api listings 
produced
by gtk-doc wrap the parameter lists down to the next line for column 
alignment.  

Is is possible to control the table column widths at all?

void          some_ridicuously_long_function_name_goes_here
                                                                                 
(parameter1, ...)    // line wrap for colume alignment!
                                                                                           

I want to pull the parameter list up and move that column over to the right.

Thanks,

Phil
