multi-select a few cells

[dragonyanglong]

Select several cells in phase panel. If Press “shift” and select a few cells, it works fine. But if press “control” (or “command” in mac) on keyboard, click a few cells. it shows:

Traceback (most recent call last):
  File "/home/ly0/Documents/billinge/dev/test_pdfgui_py3/diffpy.pdfgui/src/diffpy/pdfgui/gui/errorwrapper.py", line 59, in _f

In the gridutils.py file, only one line is changed from py2 (right) to py3 (left).

Temporary solution: comment out the problematic line of code (L78) in the diffpy utils package. It will not affect the working column or row selection. Side effect: press "control" (or command in mac) and select multi-cells, will only change the value of the first cell selected.
