package main

import "fmt"

func main() {
    for j := 1; j <= 9; j++ {
        for i := 1; i <= j; i++ {
            result := i * j
            fmt.Printf("%d * %d = %-2d ", i, j, result) //
        }
        fmt.Println()

    }

}

结果：

1 * 1 = 1  
1 * 2 = 2  2 * 2 = 4  
1 * 3 = 3  2 * 3 = 6  3 * 3 = 9  
1 * 4 = 4  2 * 4 = 8  3 * 4 = 12 4 * 4 = 16 
1 * 5 = 5  2 * 5 = 10 3 * 5 = 15 4 * 5 = 20 5 * 5 = 25 
1 * 6 = 6  2 * 6 = 12 3 * 6 = 18 4 * 6 = 24 5 * 6 = 30 6 * 6 = 36 
1 * 7 = 7  2 * 7 = 14 3 * 7 = 21 4 * 7 = 28 5 * 7 = 35 6 * 7 = 42 7 * 7 = 49 
1 * 8 = 8  2 * 8 = 16 3 * 8 = 24 4 * 8 = 32 5 * 8 = 40 6 * 8 = 48 7 * 8 = 56 8 * 8 = 64
