JAVA怎么輸出九九乘法表并要求列對齊？

public class multi {

public static void main(String[] args) {

//使用循環打印99乘法表

System.out.println("***使用循環打印99乘法表***");

for (int i = 1; i <= 9; i++) {

System.out.println("");

for (int j = 1; j <= i; j++) {

// System.out.print(i + "*" + j + "=" + i*j + "\t");

System.out.printf("%-10s",i + "*" + j + "=" + i*j ); //格式化打印流

}

}

}

}
