Since we know the maximum result can be three digits i.e 12 * 12 = 144, we can use the string formatting function when printing our output to correctly align the output. In this case, we have 3 digits as our max length, so we can format it in that particular way.

Solution:

def printMultiplicationTableFor12():
  for row in range(1, 13):
    for col in range(1, 13):
      print('{:3} '.format(row * col),end='')
    print()

Test code:

printMultiplicationTableFor12()

'''
Output:
  1   2   3   4   5   6   7   8   9  10  11  12 
  2   4   6   8  10  12  14  16  18  20  22  24 
  3   6   9  12  15  18  21  24  27  30  33  36 
  4   8  12  16  20  24  28  32  36  40  44  48 
  5  10  15  20  25  30  35  40  45  50  55  60 
  6  12  18  24  30  36  42  48  54  60  66  72 
  7  14  21  28  35  42  49  56  63  70  77  84 
  8  16  24  32  40  48  56  64  72  80  88  96

The important part was formatting of the result

IntStream.range(1, 13).forEach(i->{IntStream.range(1,13).forEach(j->{System.out.print(i*j+" ");});System.out.println("");});

/* print n*n multiplication table, and format output based on input */
    public static void printTable(int n){
        int highest = n*n;
        int tens = 1;

        highest /= 10;
        while (highest != 0){
            tens++;
            highest /= 10;
        }

        String format = "%" + tens + "s ";

        for (int i = 1; i <= n; i++) {
            for (int j = 1; j <= n; j++) {
                System.out.printf(format, i*j);
            }
            System.out.println();
        }
    }

def print_m_table(n):
char_len = len(str(n*n))+1
for row in range(1, n+1):
for col in range(1, n+1):
print(str(row*col).rjust(char_len), end="")
print()

print_m_table(20)

static void print(int n){
for(int j = 1; j<=n; j++){
for(int i = 1; i<=n; i++){
System.out.print (i * j );
