[Interest] More on table problem

[Turtle Creek Software]

If I understand this code correctly, it's putting the button inside the
cell. Unfortunately, there isn't enough room to do that.
The table only shows the QLineEdits.  When you click in a cell to edit, the
button appears next to it, over the neighboring cell(s).
However, maybe there is a container we can put the button into, that will
act as a click barrier.  Something less extreme than a dialog.
