不用存到数组，直接打印，可以减少循环操作及复杂度：
int k = 0;
for (int i = 0; i < 7; i++)
{
k = i+1;
System.out.print(k + " ");
for(int j=1;j<i+1;j++)
{
k += 7-j;
System.out.print(k + " ");
}

System.out.print("\n");
}

public static void main(String[] args) {
for(int i=1;i<8;i++){
System.out.print(i+" ");
for(int j=1,temp=i;j<i;j++,temp+=(8-j))
System.out.print(temp+(7-j)+" ");
System.out.println();
}
}
