如何对DataFrame中特定列的行进行排序？

import pandas as pd

data = {'Name': ['John', 'Emma', 'Mike', 'Sophia'],
        'Age': [25, 28, 22, 30],
        'Salary': [5000, 6000, 4500, 7000]}
df = pd.DataFrame(data)

sorted_df = df.sort_values('Salary')

sorted_df = df.sort_values('Salary', ascending=False)

print(sorted_df)

    Name  Age  Salary
3  Sophia   30    7000
1    Emma   28    6000
0    John   25    5000
2    Mike   22    4500
