2. excel库提pr: int获取cell字母

   func (biAbTestingLogic) getCellIndexByNumber(number int) string {
   	mod := number % 26      // 取模
   	quotient := number / 26 // 取商
   	if quotient == 0 {
   		return string(rune('A' + mod))
   	}
   
   	return string(rune('A'+quotient-1)) + string(rune('A'+mod))
   }

   func ColumnNumberToName(num int) (string, error) {
   	if num < MinColumns || num > MaxColumns {
   		return "", ErrColumnNumber
   	}
   	var col string
   	for num > 0 {
   		col = string(rune((num-1)%26+65)) + col
   		num = (num - 1) / 26
   	}
   	return col, nil
