Be warned though... this is one area where vscode is noticeably worse than atom or sublime; There's no alt-click-drag support so making a rectangular edit is much more work; you manually create the correct selection on each line. It's one of the few things I miss from Atom (and one of the main reasons I switched to textmate way way back).

alt+shift+click-drag mate. Drag a rectangle and hit an arrow key seems fastest to make a column.
