If you can use Numpy or Pandas, this becomes extraordinarily simple:

row = range(1, 11)
column = range(1, 11)
data = [c * r for c in column for r in row]
mat = np.array(data).reshape(10, 10)
print mat
df = pd.DataFrame(mat, columns=column, index=row)
print df

Second question answer utilizing itertools for phone number permutations:

	phone_dict = {'2': 'abc', '3': 'def', '4': 'ghi',
	'5': 'jkl', '6': 'mno', '7': 'pqr', '8': 'tuv', 
	'9': 'wxyz'}
	def word_numbers(pn):
		pn = str(pn)
		ret = ['']
		for char in pn:
			letters = phone_dict.get(char, '')
			ret = [prefix+letter for prefix in ret for letter in letters]
		return ret
	digits = '123456789'
	phone_numbers = []
	for val in permutations(digits, 7):
		phone_numbers.append(''.join(val))
	word_list = []
	for number in phone_numbers:
		word_list.append(word_numbers(number))
