It looks like I replied to Peter Uhnák directly, so I copy my message here:
If you open halo menu on topmost [in hierarchy] PanelMorph in window, you
can see that layout properties have been set properly.
By default hResizing and vResizing are set to #spaceFill in SpecTableLayout,
so:
1. rows are the same width - therefore cellPositioning doesn't matter
2. rows are occupying the whole height - therefore listCentering doesn't
matter
The following layout will allow to see effects of listCentering and
cellPositioning (btw cellPositioning is #center by default):
layout := SpecTableLayout column
cellPositioning: #center;
listCentering: #bottomRight;
newRow: [ :r | r
vResizing: #shrinkWrap;
width: 120;
add: #cell11;
add: #cell12 ];
newRow: [ :r | r
vResizing: #shrinkWrap;
add: #cell21;
add: #cell22];
yourself.
