[Feature] Explicit list_columns specification

[kmmbvnr]

Set of classes for list_columns to explicitly configure data source and column styling

    list_columns = [
       'pk', ViewsetCallable('get_object_data', width='20px', type=bool)
    ]

As an example of what I'd like to fix. There are columns being cut off while others take up a lot of empty space. I have some lists with even more columns that are affected even more.
A better automatic balancing of the column would work, or custom styling like your suggestion.

Also, allow you to specify which columns should hide on mobile etc.

Text align as well would be great.
