    你这个错了，九九乘法表是正三角，不是倒三角。
    System.out.print("1*1=1 ");
    System.out.print("1*2=2 2*2=4 ");
    System.out.print("1*3=3 2*3=6 3*3=9 ");
    System.out.print("1*4=4 2*4=8 3*4=12 4*4=16 ");
    System.out.print("1*5=5 2*5=10 3*5=15 4*5=20 5*5=25 ");
    System.out.print("1*6=6 2*6=12 3*6=18 4*6=24 5*6=30 6*6=36 ");
    System.out.print("1*7=7 2*7=14 3*7=21 4*7=28 5*7=35 6*7=42 7*7=49 ");
    System.out.print("1*8=8 2*8=16 3*8=24 4*8=32 5*8=40 6*8=48 7*8=56 8*8=64 ");
    System.out.print("1*9=9 2*9=18 3*9=27 4*9=36 5*9=45 6*9=54 7*9=63 8*9=72 9*9=81 ");

    up 一下：
    `javascript
    const dp = new Array(10)
    .fill(0)
    .map((x, i) =>
    new Array(10)
    .fill(0)
    .map((y, j) => (i > 0 && j > 0 && i >= j ? `${i}*${j}=${i * j}` : 0))
    .filter(x => x !== 0)
    )
    .map(x => x.join(" "))
    .filter(x => x !== "")
    .join("\n");

    console.log(dp);

    java 的，这东西有什么意义么

    for(int x=1;x<=9;x++){
    System.out.print("\n");
    for (int y=1;y<=9;y++){
    int z=x*y;
    System.out.print(x+"*"+y+"="+z+"\t");
