Pascal's triangle 2d array - formatting printed output

Question

I have a small assignment where I have to use a 2d array to produce Pascal's triangle. Here is my code, and it works. there is an extra credit opportunity if I display the triangle like so:

however, my spacing is not formatted like that. it simply displays the numbers all lined up on the left. its hard to describe but if you run it you will see what I mean.

here is my code:

import java.util.*; 

public class Pascal { 
 public static final int ROW = 16;

 public static void main(String[] args) { 
      int[][] pascal  = new int[ROW +1][];
    pascal[1] = new int[1 + 2];
    pascal[1][1] = 1;
    for (int i = 2; i <= ROW; i++) {
        pascal[i] = new int[i + 2];
        for (int j = 1; j < pascal[i].length - 1; j++) {
            pascal[i][j] = pascal[i-1][j-1] + pascal[i-1][j];
            }
    }
    for (int i = 1; i <= ROW; i++) {
        for (int j = 1; j < pascal[i].length - 1; j++) {
            System.out.print(pascal[i][j] + " ");
        }
        System.out.println();
    }
}
}

if someone could help me figure out how to add the correct spacing to my program to produce the output desired in the picture, that would be great :) I know I need to put a system out print " " somewhere I just dont know where. thanks!
