LineBox is easy, and vertical lines aren't too difficult:
vline = urwid.SolidFill(u'\u2502')
# put it between two box widgets
boxcol = urwid.Columns([boxwidget1, ('fixed',1,vline), boxwidget2])
# put it between two flow widgets
flowcol = urwid.Columns([flowwidget1, ('fixed',1,vline), flowwidget2],

That depends on what you want.
Currently the "up", "down", "page up" and "page down" keys are hard
coded into the ListBox widget and the "up" and "down" keys are hard
coded into the Pile widget.
You can translate "j" and "k" to "down" and "up" if they aren't handled
by an edit widget or similar with code like:
# ... part of your main loop
for k in self.ui.get_input():
# (not shown) do urwid.is_mouse_event stuff..
k = self.view.keypress(size, k)
if k == "j":
if k == "k":
If that's not what you're looking for, would you tell me what behaviour
you want when the user presses the "up" and "down" keys?
