You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: 14_多重循环控制.go
    path of file: ./repos/learning/golang/source_code/Go语言基础与提升课程资料/源码
    
    the code of the file until where you have to start completion: package main

import "fmt"

func main() {
	for i :=
    
func main() {
	for i := 1; i < 10; i++ { //i:代表的是行
		for j := 1; j <= i; j++ { //j:代表的是列
			fmt.Printf("%d*%d=%d\t", j, i, i*j)
		}
		fmt.Println()
	}
}
