Are you doing this in the resource editor? I enter a list of strings 
into the field 'columnHeadings':
          ['Name', 'Age', 'Address']
and enter data into the field 'items':
          [['John', '21', 'London'], ['George', '34', 'Liverpool'], 
['Paul', '63', 'Paris']]
and everything is otherwise OK, but the columns change to be too narrow. 
That is maybe what you meant with this:

I started looking for info to solve this problem through the usual route:
    - Pythoncard Sample Launcher,
    - wxPython Demo
    - wxWidgets reference (installed with wxPython)

The last one helped: its documentation of the wxListCtrl widget gives 
the function SetColumnWidth, which I called in the on_initialize method 
like this:
        self.components.MultiColumnList1.SetColumnWidth(0,70)
        self.components.MultiColumnList1.SetColumnWidth(1,45)
to set the 'Name' and 'Age' column widths.

BTW1. Both the Pythoncard and the wxPython demos are a great source of 
information because you are able to browse the source code to see how 
the widgets are used and read the comments. In this particular case the 
Pythoncard demo has a demo called 'multicolumnexample' that at the start 
of its source has some documentation on the multicolumlist component.

BTW2. wxPython is built on the wxWidgets package. Thus the wxWidgets 
reference is applicable to Pythoncard also. Reading it may be a little 
rough at first because the documentation is made on the C++ level. After 
a while, though, you get used to how to apply mutatis mutandis the info 
in Pythoncard.
