Gettiing issues while using SQL kernel and trying to display a table

When using a SQL kernel with ipywidgets through BeakerX, i am getting an error when trying to display a table. I can pull information from the table like
```sql
SELECT population FROM world
WHERE name = 'Germany';
```
I get back that specific value

but if i run

```sql
SELECT name, population FROM world
WHERE name IN ('Sweden', 'Norway', 'Denmark');
```

i get the error

`No renderer could be found for output. It has the following MIME types: method, application/vnd.jupyter.widget-view+json`

i checked the version with:

```python
import ipywidgets
ipywidgets.__version__
```
and get back `7.4.2`
and i did run `jupyter nbextension enable --py --sys-prefix widgetsnbextension` and it validated properly.
I am not sure what is wrong.
