     2         for(int i = 1; i < 10 ; i ++){
     3             for(int k = 1; k < i ; k ++){
     4                 System.out.print("\t");
     5             }
     6             for(int j = i; j < 10 ; j ++){
     7                 System.out.print(i+"×"+j+"="+i*j+"\t");
     8             }
     9             System.out.println();
    10         }
