DOC: code example isn't formatted in `pandas.DataFrame.to_sql`

[hkennyv]

Location of the documentation

The code example in pandas.DataFrame.to_sql isn't formatted properly.

(it's the example that inserts User 4 and User 5 into the db)

Note: You can check the latest versions of the docs on master here.

Documentation problem

oh no, the code isn't formatted correctly!

Suggested fix for documentation

The reason is there's no blank line before the code snippet, see:

pandas/pandas/core/generic.py

Lines 2692 to 2695 in b58ee57

	An `sqlalchemy.engine.Connection` can also be passed to to `con`:
	>>> with engine.begin() as connection:
	... df1 = pd.DataFrame({'name' : ['User 4', 'User 5']})
	... df1.to_sql('users', con=connection, if_exists='append')

Add a blank line above the code snippet :), i have a PR in progress
