I think you should just shut off FasterCSV's conversion, since it isn't doing what you want.  table() is just a simple shortcut:

    # 
    # A shortcut for:
    # 
    #   FasterCSV.read( path, { :headers           => true,
    #                           :converters        => :numeric,
    #                           :header_converters => :symbol }.merge(options) )
    # 
    def self.table(path, options = Hash.new)
      read( path, { :headers           => true,
                    :converters        => :numeric,
                    :header_converters => :symbol }.merge(options) )
    end

So just call read() yourself and leave out the :converters => :numeric option.

Hope that helps.
