input: Write a function to generate a multiplication table for a given range of numbers, including the start and end parameters.
  def multiplication_table(start, end):
  	for x in range(start, end + 1):
  		for y in range(start, end + 1):
  			print(x * y, end = "  ")
  		print("\n")
  
  assert multiplication_table(5, 10) # should print a multiplication table from 5 to 10
  assert multiplication_table(2, 4) # should print a multiplication table from 2 to 4
  assert multiplication_table(1, 3) # should print a multiplication table from 1 to 3
  assert multiplication_table(7, 9) # should print a multiplication table from 7 to 9
  assert multiplication_table(3, 6) # should print a multiplication table from 3 to 6
output: def multiplication_table(start, end):
  	for x in range(start, end + 1):
  		for y in range(start, end + 1):
  			print(x * y, end = "  ")
  		print("\n")
