        /*    fmt.Printf("第%d次：\n",m) */
        for n := 1; n <= m; n++ {
            fmt.Printf("%dx%d=%d ", n, m, m*n)
        }
        fmt.Println("")
    }

func main() {

    gotoTag()
}

//嵌套for循环打印九九乘法表
func print9x() {
    for m := 1; m < 10; m++ {
        for n := 1; n <= m; n++ {
            fmt.Printf("%dx%d=%d ", n, m, m*n)
        }
        fmt.Println("")
    }
}

//for循环配合goto打印九九乘法表
func gotoTag() {
    for m := 1; m < 10; m++ {
        n := 1
    LOOP:
        if n <= m {
            fmt.Printf("%dx%d=%d ", n, m, m*n)
            n++
            goto LOOP
        } else {
            fmt.Println("")
        }
        n++
    }
}

输出结果
