用Java写出下图的九九乘法表

Question

已写了大概的代码，但不知道如何得出如图所示的结果
public static void main(String[] args) {

    for(int i=1;i<=9;i++){
           for(int j=1;j<=i;j++){
               System.out.print(j+" "+i+"  "+(i*j)+"\t");
           }
           System.out.println(" ");
       }
}

}

package com;

public class Main {

    public static void main(String[] args) {
        
        System.out.println("             99乘法表                ");
        System.out.println("   1  2  3  4  5  6  7  8  9");
        System.out.println("____________________________________");
        System.out.println();
        for (int i = 1; i <= 9; i++) {
            for (int j = 1; j <= i; j++) {
                if (j == 1) {
                    System.out.print(i + "| " + i * j + " ");
                } else {
                    System.out.print(i * j + " ");
                }
            }
            System.out.println(" ");
        }
    }

}
