I have the following dataframe:

```
import pandas as pd

df = pd.DataFrame({'text': ['foo foo', 'bar bar'],
                 'number': [1, 2]})
df

```

How do I center-align both the column titles/headers and the values in a dataframe, and how do I drop the index (the column with the values 0 and 1) in a dataframe?
