# xlsx生成器
1. 通过接口实现xlsx输出与数据生成逻辑的分离
1. 强大的列名生成器，只需通过标题定位列，免去生成列名的困扰
1. 标题支持子标题，支持多Sheet
1. xlsx生成文件还是通过网络输出，使用场景自主决定
1. 通过提供adapter实现通用接口函数，减少实现代码
## 接口定义
```go
type XlsxGenerator interface {
/// 在输出整个xlsx之前调用，在这里可以做一些输出准备工作
BeforeOutputXlsx()
/// 获取输出目标
GetWriter() io.Writer
/// 获取Book的sheet名称
GetSheets() []string
/// 获取某一个sheet的标题及子标题
GetTitles(sheet string) []Title
// 获取某个sheet所有的输出行channel
GetRows(sheet string) (<-chan map[string]interface{}) // 如果没有subtitle，key={title}; 其它key为{title}_{subtitle}
}
```
## 例子
```go
package main
import (
"github.com/rosbit/xlsx-generator"
"os"
"io"
"fmt"
)
func main() {
fp, err := os.Create("a.xlsx")
if err != nil {
fmt.Printf("failed to create a.xlsx: %v\n", err)
return
}
defer fp.Close()
xg := &xlsxTest{fp:fp}
toxlsx.GenerateXlsx(xg);
}
// ---- XlsxGenerator implementation ----
type xlsxTest struct {
toxlsx.DummyXlsxGeneratorAdapter
fp *os.File
}
func (t *xlsxTest) GetWriter() io.Writer {
return t.fp
}
func (t *xlsxTest) GetSheets() []string {
return []string{"Sheet1", "Sheet2"}
}
func (a *xlsxTest) GetTitles(sheet string) []toxlsx.Title {
return []toxlsx.Title{
toxlsx.Title{
Name: "a",
},
toxlsx.Title{
Name: "b",
SubTitles: []string {
"b1", "b2", "b3",
},
},
toxlsx.Title{
Name: "c",
},
}
}
func (a *xlsxTest) GetRows(sheet string) (<-chan map[string]interface{}) {
rows := make(chan map[string]interface{})
go func() {
for i := 0; i < 10; i++ {
r := i+1
row := make(map[string]interface{}, 5) // a, {b1,b2,b3}, c -> 5
row["a"] = fmt.Sprintf("a%d%d", r, 1)
row["b_b1"] = fmt.Sprintf("b%d%d", r, 2)
row["b_b2"] = fmt.Sprintf("b%d%d", r, 3)
row["b_b3"] = fmt.Sprintf("b%d%d", r, 4)
row["c"] = fmt.Sprintf("c%d%d", r, 5)
rows <- row
}
close(rows)
}()
return rows
}
```
## 运行结果
生成a.xlsx，内容如图
