Discovered a strange bug.

[podmask]

Description
There is the code :

func TestMyTest(t *testing.T) {
	f, err := excelize.OpenFile("../test.xlsx")
	if err != nil {
		fmt.Println(err)
		return
	}
	defer f.Close()

	f.SetCellValue("Sheet1", "D24", "2001")
	f.SetCellFormula("Sheet1", "D25", `IF(D24<>"","、"&D24,"")`)
	f.SetCellFormula("Sheet1", "E25", `IF(E24<>"","、"&E24,"")`)
	f.SetCellFormula("Sheet1", "B27", `IF(D25&E25<>"",D25&E25,"")`)

	value, err := f.CalcCellValue("Sheet1", "D25")
	if err != nil {
		fmt.Println(err)
		return
	}
	t.Log("D25:", value)

	value, err = f.CalcCellValue("Sheet1", "E25")
	if err != nil {
		fmt.Println(err)
		return
	}
	t.Log("E25:", value)
	value, err = f.CalcCellValue("Sheet1", "B27")
	if err != nil {
		fmt.Println("B27 err:", err)
	}
	t.Log("B27:", value)
}
