Pandas DataFrame：同时抑制科学计数法和操作边框样式？

Question

I am using the Python packages pyodbc and pandas. I have pulled some data from a SQL query into a dataframe and am attempting to get a tabular view of the dataframe with two characteristics:

1. Numeric columns are displayed with a specified decimal precision and no scientific notation.
2. Column borders are thick and black.

Can anyone help me to do this? I am working in Jupyter-Notebook, Python v3.6.5. Here is my code so far. It gives me criterion #2 but not #1. If I run the last line which is currently commented out, I get criterion #1 but not #2.

import pyodbc as po
import pandas as pd
pd.set_option('display.float_format', '{:.5f}'.format)
conn=po.connect(DRIVER = '{SQL Server}',
                      SERVER = 'xxx',
                      DATABASE = 'yyy')
query_VD01="""select 1 union select 0.000001 union select 1000000"""

VD01=pd.read_sql(query_VD01,conn)
VD01.style.set_properties(**{'border-style':'solid'})
#display(VD01)

edit - I want 6 digits of decimal precision. Here is the result of running VD01.head():

0   0.00000
1   1.00000
2   1000000.00000

If I had set display.float_format to {:.6f} I instead get this from VD01.head():

0   0.000001
1   1.000000
2   1000000.000000

Answer 1

chain together the style and you get what you want.

VD01 = pd.DataFrame([0.000001,1.000000,1000000.000000])
VD01.style.format("{:.6f}").set_properties(**{'border-style':'solid'})
