Giving a data frame a title and styling columns with Pandas Python-CodePudding

I want to give dict_val dataframe a title that is placed in the center title. I am also trying to separate the each 3 digits with a comma on the Numbers column how would I be able to give a dataframe a title and style the a column as such and get the Expected Output below?

import pandas as pd
import numpy as np

title = 'Number and Numbers 2 Comparison'
numbers = np.array([123242737.4923,679754672.3849]) 
numbers2 = np.array([123523,467895]) 

dict_val = pd.DataFrame({'Numbers':numbers.round(2),'Numbers 2': numbers2})
display(dict_val)

Output:

Expected output:

  Number and Numbers 2 Comparison
    Numbers         Numbers 2
0   123,242,737.49  123523
1   679,754,672.38  467895

CodePudding user response：

Use Styler.format:

dict_val.style.format(formatter={'Numbers': '{:,.2f}'})

Create MultiIndex and set styles for alignment to center:

text = 'Number and Numbers 2 Comparison'

dict_val.columns = pd.MultiIndex.from_product([[text], dict_val.columns])
print (dict_val)
  Number and Numbers 2 Comparison          
                          Numbers Numbers 2
0                    1.232427e 08    123523
1                    6.797547e 08    467895

css = [ {'selector': 'th.col_heading.level0', 'props': 'text-align: center;'}]
dict_val.style.set_table_styles(css, overwrite=False).format(formatter={(text, 'Numbers'): '{:,.2f}'})
