DataViewer for pandas dataframes is not usable at all

• Notebooks (.ipynb files)
• Interactive Window and/or Cell Scripts (.py files with #%% markers)

What happened?

Let's say that I am debugging a test and I would like to see the dataframe content:

If I open it in DataViewer it looks like this:

1. opening of the dataframe in DataViewer is very slow
2. it is opened in the tab instead to be in a separate window as wide as possible with maximum hight
3. all columns are too narrow (about 10 characters wide) and there is no way to adjust a single column or all columns width to their contents

If I widen columns by hand:

After pressing "refresh", columns are narrow again.

Now consider this dataframe as toy example. Try to think how this would look like if I have a dataframe with 10 millions of rows and 100 columns (which is something quite usual in data science world).

PyCharm has a solution for it:

1. showing a dataframe is fast
2. it is opened in its own window that you can enlarge at will
3. all columns are much wider and they can be even resized automatically

Until you solve these problems, no one will use DataViewer for dataframes in vscode.
