lost table name with session when insert multiple Slice

[marionzheng]

Code:

type NightlyRate struct {
	ID int64 `xorm:"'id' not null pk BIGINT(20)" json:"id"`
}

func (NightlyRate) TableName() string {
	return "prd_nightly_rate"
}

trans := db.NewSession()
defer trans.Close()
_ = trans.Begin()

rtArr := []interface{} {
	[]*model.NightlyRate {
		{ID: 1},
		{ID: 2},
	},
	[]*model.NightlyRate {
		{ID: 3},
		{ID: 4},
	},
	[]*model.NightlyRate {
		{ID: 5},
	},
}
tableName := `prd_nightly_rate_16`
_, err := trans.Table(tableName).Insert(rtArr...)
if nil != err {
	println(err.Error())
	_ = trans.Rollback()
}

_ = trans.Commit()

Result:
