TableAPI for integer vs formatted integer

In Python, how do I change a column in the TableDisplay to use "integer" format rather than "formatted integer"?

My best guess was:

```python
import pandas as pd
from beakerx import *

df = pd.DataFrame({'a': [10000]})
table = TableDisplay(df)
table.setStringFormatForColumn('a', 'integer')
```

I don't see anything relevant in [`tableitems.py`](https://github.com/twosigma/beakerx/blob/master/beakerx/beakerx/tabledisplay/tableitems.py)
