qgrid does not display correctly in voila served notebooks
I'd like to use qgrid to work with dataframes in voila served notebooks.
I have a simple single cell notebook
import qgrid
import numpy as np
import pandas as pd
df = pd.DataFrame(np.random.rand(3,5))
qg = qgrid.show_grid(df)
qg
and this works fine in the Jupyter rendered notebook:

$ voila qgrid.ipynb

The qgrid widget does display, but it doesn't respect the size of the window like it does when it is displayed in the Notebook:

rather the dataframe is stretched super wide and the user has to scroll over.
I can work around this with qg = qgrid.show_grid(df, grid_options={'forceFitColumns': False, 'defaultColumnWidth': 100}):

but that's not ideal as the widget still extends and it doesn't look nice.
Thanks for taking a look and for a great package.
Interim fix: Wrapping it in a ipywidgets.HBox or similar forces it to be contained.
HBox([qg], layout={'width': '250px'})
HBox([qg], layout={'width': '250px'}) does not work. it hangs and does not move from "loading widget..."
