        "name": ['安全能力等级', "一级", "√"],
        "name1": ["", "二级", "√"],

        "name3": ["", "四级", "√"],
        "age": ["", "五级", "√"],
    })



    df2 = df.replace('', None)
    df2 = df2.fillna(method='pad', axis=0)
    df2 = df2.fillna(method='pad', axis=1)
    df2 = df2.fillna(method='backfill', axis=1)
    df2 = df2.fillna(method='backfill', axis=0)

    print(df2)
