Why isn't this Java formatting result warranted?

I am a beginner and I am experimenting with formatted output.
I am trying to create a decimal place table:

for (int i = 0; i < 8; i++) {
  for (int j = 0; j < 8; j++) {
    row = (double) 5*i;
    column = (double) j + 1;
    System.out.format("% 6.3f", row/column);
    System.out.print("\t");
  }
  System.out.format("%n");
}

      

        
        
        
      

    

This gives:

 0.000   0.000    0.000   0.000   0.000   0.000   0.000   0.000 
 5.000   2.500    1.667   1.250   1.000   0.833   0.714   0.625 
 10.000 5.000    3.333   2.500   2.000   1.667   1.429   1.250  
 15.000 7.500    5.000   3.750   3.000   2.500   2.143   1.875  
 20.000 10.000   6.667   5.000   4.000   3.333   2.857   2.500  
 25.000 12.500   8.333   6.250   5.000   4.167   3.571   3.125  
 30.000 15.000   10.000  7.500   6.000   5.000   4.286   3.750  
 35.000 17.500   11.667  8.750   7.000   5.833   5.000   4.375  

      

        
        
        
      

    

The API says that if the "-" flag is not thrown, then the result will be correct, which is what I want. I put '' after% to indicate that I want the output to be padded with spaces when needed. What am I missing?
