如何对齐单元格中的文本以使其居中?
代码:
import matplotlib.pyplot as plt
from pandas.tools.plotting import table
import pandas as pd
#My dataframe
df = pd.DataFrame({
'Weeks' : [201605, 201606, 201607, 201608],
'Computer1' : [50, 77, 96, 100],
'Computer2' : [50, 79, 100, 80],
'Laptop1' : [75, 77, 96, 95],
'Laptop2' : [86, 77, 96, 40],
'Phone' : [99, 99, 44, 85],
'Phone2' : [93, 77, 96, 25],
'Phone3' : [94, 91, 96, 33]
})
df2 = df.set_index('Weeks') #Makes the column 'Weeks' the index.
#Make a png file out of an dataframe.
plt.figure(figsize=(9,3))
ax = plt.subplot(211, frame_on=False) # no visible frame
ax.xaxis.set_visible(False) # hide the x axis
ax.yaxis.set_visible(False) # hide the y axis
colors = df2.applymap(lambda x: 'green' if x>= 80 else 'red').reset_index().drop(['Weeks'], axis=1)
tbl = table(ax, df2, loc='center',
cellColours=colors.as_matrix(),
colColours=['black']*len(colors.columns),
rowColours=['black']*len(colors))
tbl._cells[1, -1]._text.set_color('white')
tbl._cells[2, -1]._text.set_color('white')
tbl._cells[3, -1]._text.set_color('white')
tbl._cells[4, -1]._text.set_color('white')
tbl._cells[0, 0]._text.set_color('white')
tbl._cells[0, 1]._text.set_color('white')
tbl._cells[0, 2]._text.set_color('white')
tbl._cells[0, 3]._text.set_color('white')
tbl._cells[0, 4]._text.set_color('white')
tbl._cells[0, 5]._text.set_color('white')
tbl._cells[0, 6]._text.set_color('white')
plt.show()
