Autostretch last column of GridViews to fill empty space

[harry-cpp]

It would be nice if the last column of GridView and TreeGridView got stretched to fill the remaining space like on the other platforms, right now it looks rather silly:

Thanks for submitting the issue! It would be good if it were not just the last column, but the ability to specify which column(s) should fill the remaining space.

Only the last column can fill the remaining space, anything but that would create a lot, and I say A LOT of problems regarding how bottom scrollbar functions and how the other grid columns react to resizing some columns.

Hm, that's unfortunate, since I can envision scenarios where you'd want a few columns to the right of the expanding column. macOS supports this scenario which is used in Finder, for example:

It's not impossible to do, but I do think it's gonna be hard, reason being is that you have an AutoSize property which expands the cell enough so everything in it is visible, but if you set that cell property to also fill empty space, in WPF those are 2 different sizing markers so you come to a problem with the face that you can follow only one of those, but you need both for something like TreeGridView.

But what about ability to set the column widths? And maybe by reflection lastColumn.width = grid.width - otherColums.width?
