/* Notes

   (1) Limits the size of the multiplication table to be within
       the range 9 to 16.
   (2) Output a list of number as the header line of the table.
   (3) Draw a line to separate the table header and content.
   (4) Outer 'for' loop
   (5) Output the row number and a vertical line.
   (6) Inner 'for' loop to output each values in the table.
   (7) Jump to next line when a row of data is printed.
