edit cell value issues when column name has special characters

[TC500]

import pandas as pd
import dtale
import dtale.app as dtale_app
dtale_app.JUPYTER_SERVER_PROXY = True
PROXY_ROOT='/mtjupyter/user/xxx/'
df = pd.DataFrame({'-.:?\/|test':[1,2,3]})
dtale.show(df,notebook=True,ignore_duplicate=True,app_root=PROXY_ROOT)

when i edit cell value, something like A1 from 1 to 0, the backend raise exception below:

Traceback (most recent call last):
  File "/conda/envs/notebook/lib/python3.6/site-packages/pandas/core/indexes/base.py", line 2898, in get_loc
    return self._engine.get_loc(casted_key)

The above exception was the direct cause of the following exception:

@TC500 I'm sorry about that. I was hoping I wouldn't have to patch my API endpoints but it looks like I do. I've gone through the code and modified any endpoint which included a column name in the URI path and instead passed it as a URL parameter. That should solve this issue. Should have a release out later today:

complex_name_edit.mov

Thanks for your patience

Just released v1.44.1 to pypi with this fix. Should be on conda-forge soon
