Add some methods in column to set the sort order. Look at associated_limit for
example:
# to set how many associated records a column with plural association must
show in list
cattr_accessor :associated_limit
@@associated_limit = 3
attr_accessor :associated_limit
.....
def initialize(...)
...
@associated_limit = self.class.associated_limit
...
end
To pass the option add a third parameter, and change method calls to pass the
option
