Answer 1

I created a package to write properly formatted excel tables from pandas: pandas-xlsx-tables

from pandas_xlsx_tables import df_to_xlsx_table
import pandas as pd

data = [10, 20, 30, 40, 50, 60, 70, 80]
df = pd.DataFrame({'Rank': data,
                'Country': data,
                'Population': data,
                'Strings': [f"n{n}" for n in data],
                'Datetimes': [pd.Timestamp.now() for _ in range(len(data))]})

df_to_xlsx_table(df, "my_table", index=False, header_orientation="diagonal")

You can also do the reverse with xlsx_table_to_df

Answer 2

Here is one way to do it using XlsxWriter:

import pandas as pd

# Create a Pandas dataframe from some data.
data = [10, 20, 30, 40, 50, 60, 70, 80]
df = pd.DataFrame({'Rank': data,
                   'Country': data,
                   'Population': data,
                   'Data1': data,
                   'Data2': data})

# Create a Pandas Excel writer using XlsxWriter as the engine.
writer = pd.ExcelWriter("pandas_table.xlsx", engine='xlsxwriter')

# Convert the dataframe to an XlsxWriter Excel object. Turn off the default
# header and index and skip one row to allow us to insert a user defined
# header.
df.to_excel(writer, sheet_name='Sheet1', startrow=1, header=False, index=False)

# Get the xlsxwriter workbook and worksheet objects.
workbook = writer.book
worksheet = writer.sheets['Sheet1']

# Get the dimensions of the dataframe.
(max_row, max_col) = df.shape

# Create a list of column headers, to use in add_table().
column_settings = []
for header in df.columns:
    column_settings.append({'header': header})

# Add the table.
worksheet.add_table(0, 0, max_row, max_col - 1, {'columns': column_settings})

# Make the columns wider for clarity.
worksheet.set_column(0, max_col - 1, 12)

# Close the Pandas Excel writer and output the Excel file.
writer.save()

Output:

Update: I've added a similar example to the XlsxWriter docs: Example: Pandas Excel output with a worksheet table
