# Functions
*
* Assign 结构体赋值
*
* Example:
*
* type User1 struct {
* Name string
* Age int
* }
*
* type User2 struct {
* Name string
* Age int
* }
*
* u1 := &User1{Name: "zhangsan", Age: 20}
* u2 := &User2{}
*
* Assign(u1, u2)
* fmt.Println(u1, u2)

max-min=days DtSub(20200302, 20200301) = 1.
*
* ExportExcel 生成excel
*
* Example:
*
* type ReportExcel struct {
* Dt string `excel:"日期"`
* NewUsers int64 `excel:"注册人数"`
* LoginUsers int64 `excel:"登录人数"`
* Tmp int64 `excel:"-"`
* }
* tbody := []ReportExcel{
* {"2006-01-02", 1, 2},
* }
* buf, err := ExportExcel(ReportExcel{}, tbody)
* if err != nil {
* //
* }
* ioutil.WriteFile("test.xlsx", buf.Bytes(), 0644)
