Guide for creating the table: ()
- Outer Borders should be created with '-', '+', and '|' characters
- inner borders should be created with '.' character

- total width of bill: 60 excluding borders
- Grand Total should have the width of the bill and should be justified right
- headers and footers should be justified center

- you can call function print_item_row() to print each item in the row.
  you can change the function itself to print in your own format.

hints:

print('+', '-' * 60, '+', sep='')
print('|', 'ABC Shop'.center(60), '|', sep='')
print('|', '.' * 60, '|', sep='')
print('|', '  Order Invoice for: John Doe'.ljust(60), '|', sep='')
print('|', '.' * 60, '|', sep='')
