Jupyter中的Pandas DataFrames:等宽且居中的列 [英] Pandas DataFrames in Jupyter: columns of equal width and centered

问题描述

我正在使用Jupyter Notebooks，并且希望显示一个对所有列都应用相同宽度且所有值都居中的pandas DataFrame.在不导入库的情况下最简单的方法是什么?

Am using Jupyter Notebooks and would like to display a pandas DataFrame applying the same width to all the columns, with all values centered. What's the simplest way to achieve this, without importing libraries?

import pandas as pd
raw_data = {'regiment': ['Nighthawks', 'Dragoons'], 
    'company': ['1st', '2nd'], 
    'name': ['Miller', 'Jacob'], 
    'preTestScore': [4, 24],
    'postTestScore': [25, 94]}
df = pd.DataFrame(raw_data, columns = ['regiment', 'company', 'name', 'preTestScore', 'postTestScore'])
df

推荐答案

pandas 0.17.1中的新功能是 pd.Styler :

New in pandas 0.17.1 is the pd.Styler:

raw_data= {'regiment': ['Nighthwawks','Dragons'],
            'company':['1st','2nd'],
            'name':['Miller', 'Ali'],
            'preTestScore':[4,120]}
df = pd.DataFrame(raw_data)

d = dict(selector="th",
    props=[('text-align', 'center')])

df.style.set_properties(**{'width':'10em', 'text-align':'center'})\
        .set_table_styles([d])
