Feature request: Pin column when scrolling sideways in data view

It would be incredibly useful if it was possible to pin a column, when scrolling sideways.

E.g you view the data in a table with people. You could pin the person name/ID column, so when you scroll sideways, you always see which row you are looking at.

♥ I vote + to this feature!

VirtualTree does not really support multiple fixed (or pinned) columns. The first column can already contain the row id which is always fixed. I just defined column 5, 10 and 13 testwise as fixed, which results in a non-expected behaviour - see attached animation.
