Thanks for the pointers Ken.
I found strscan ..so my 1st implementation is:
require 'strscan'



  table_file = StringScanner.new( File.read("code") )
  while line = table_file.scan_until(/\w+|\W+/)
       table=line
       if ( line =~ /Table/ ) and
          ( /\w+.+\(.+\)/ =~ line = table_file.scan_until(/\{/) )
             left_brackets=1
             right_brackets=0
             table << line
             temp=""
              until left_brackets == right_brackets do
                 temp = table_file.getbyte
                 case temp
                 when "}"
                    right_brackets+=1
                 when "{"
                    left_brackets+=1
                 end
                 table << temp
              end
               puts table
               puts "*******"
       end
  end
