Description of Issue

The following code runs fine in a jupyter notebook, but fails when using Voila, and gives several 404 errors listed below.

from ipywidgets import widgets
import pandas as pd
import qgrid
df=pd.DataFrame([[1,2,3],[2,3,4]], columns=['1','2','4'])
qg=qgrid.QGridWidget(df=df)
display(qg)

Errors (From Chrome JS console):

• What did you expect to happen?
  A beautifully displayed dataframe to appear in my webapp
• What happened instead?
  A bank page, with several 404 errors in the javascript console, in the process learned the the latest version of qgrid on unpkg.com is 1.1.1.

Reproduction Steps

1. pip install qgrid
2. paste code listed above
3. press voila button

I looked through the other issues, it seems like others have had similar issues, I have yet to find a fix.

qgrid and voila are pretty awesome I'm hoping to get them working together.
