添加编码格式：

encoding='utf_8_sig'

def saveColumnNameToCSV(OSSPath,rowsInfo):
    with open(OSSPath,"w",newline='',encoding='utf_8_sig') as f:
        headers=["No","OSS","License","Feature","Type","Version","Encription","Modification","Comment","Homepage","License in statement ","Link to License template"]
        fcsv = csv.DictWriter(f,headers)
        fcsv.writeheader()
        fcsv.writerows(rowsInfo)

##rowinfos是一个list类型
##[ {"NO":1,"OSS":2,,,,"Link to License template":3} 
## {"NO":3,"OSS":4,,,,"Link to License template":5} ]
