这段程序怎么回事啊

public static void main(String[] args) {
System.out.println(" multiplication table");
System.out.println("--------------------------------");

System.out.print(" |");
for(int j=1;j<=9;j++)
System.out.print(" "+j);

for(int i=1;i<=9;i++)
{System.out.print(i+" |");
for(int j=1;j<=9;j++)
{
if(i*j<10)
System.out.print(" "+i*j);
else
System.out.print(" "+i*j);
}
System.out.println();
}
}
}
这段程序正常应该输出:
multiplication table
--------------------------------
| 1 2 3 4 5 6 7 8 9
2 | 2 4 6 8 10 12 14 16 18
3 | 3 6 9 12 15 18 21 24 27
4 | 4 8 12 16 20 24 28 32 36
5 | 5 10 15 20 25 30 35 40 45
6 | 6

public static void main(String[] args) {
System.out.println(" multiplication table");
System.out.println("--------------------------------");

System.out.print(" |");
for(int j=1;j<=9;j++)
System.out.print(" "+j);
System.out.println();

for(int i=2;i<=9;i++)
{System.out.print(i+" |");
for(int j=1;j<=9;j++)
{
if(i*j<10)
System.out.print(" "+i*j);
else
System.out.print(" "+i*j);
}
System.out.println();
}
}
}
看看现在对不对
