Table view column labels do not line up

In the following example, why don't the column labels line up correctly?

| builder windowSpec gridModel gridSpec tableInterface |
builder := UIBuilder new.
builder window: ApplicationWindow new.
windowSpec := WindowSpec label: 'my window'.
builder add: windowSpec.
gridModel := TwoDList on: #(
'c1 r1' 'c2 r1' 'c3 r1' 'c4 r1' 'c5 r1'
'c1 r2' 'c2 r2' 'c3 r2' 'c4 r2' 'c5 r2'
'c1 r3' 'c2 r3' 'c3 r3' 'c4 r3' 'c5 r3'
'c1 r4' 'c2 r4' 'c3 r4' 'c4 r4' 'c5 r4'
) columns: 5 rows: 4.
tableInterface := TableInterface new selectionInTable:
(SelectionInTable with: gridModel).
tableInterface columnLabelsArray: #('Column 1' 'Column 2' 'Column 3'
'Column 4' 'Column 5').
gridSpec := (TableViewSpec new)
layout: (10@45 extent: 280@150);
name: #graphPane;
model: tableInterface;
yourself.
builder add: gridSpec.
builder openWithExtent: 300@240 andType: #normal

What do you mean by "not line up correctly" ? Do you mean that the column headers appear to be centered over the columns, but the column entries are left aligned?

Re: Table view column labels do not line up

The column labels don't line up. They aren't the same width as the
cells below them. It isn't related to justification.

Like this one?

Mine doesn't show the problem. Which is a great demonstration of just why a picture is SOOO worth a 1000 words. On Windows, the code is stretching the 5 labels evenly over the entire list, scrollbar width included. And down in the list zone, it's doing them uniformly across the width minus the scrollbar. If you use a layout: argument of (0 @ 0 corner: 1@1) asLayout, you get a resizable layout bound to the window size, so you can change the size and watch the effect. On OSX, it will clip the labels to rightmost point to the left side of the right scrollbar. Whereas your screenshot shows that in its case, the rightmost clip of the labels is the *right* side of the right scrollbar.

I don't see at first glance of the code why this is happening. Someone (possibly even me) will have to glare a little harder at it.
