I actually prefer it this way. A solution which is less complex and easy 
to use. I think in Squeak a Squeak morph which uses a TableLayout 
LayoutPolicy is a misnomer.

It only acts as a table if you have submorphs of fixed width and pay 
attention how you add them in regards to the total width of the morph. 
In fact does a flow layout.

Amazing demo what is now possible in terms of editing/annotating in your 
Dynabook application.

I assume you use the FlowLayoutMorph in the flap you open at the end.

There are many morph classes which have longer names.

If I search for a class and give as class name fragment 'Layout' it will 
appear in the choices together with LayoutAdjustingMorph, LayoutMorph 
and LayoutSpec.

So Layout related classes will be easily found. So I suggest to go for 
the name 'FlowLayoutMorph'.

I did an example which mimics table layout behavior as all the item 
morphs are of the same size

example1b
"
     self example1b
"
     | table cells |
     table := self new openInWorld.
     cells := OrderedCollection new.
     30 timesRepeat: [ |cellContent cellContentExtent cell  |
              cellContentExtent := (15 to: 80) atRandom asPoint.
              cellContent := (ColoredBoxMorph new ::
                     morphExtent: cellContentExtent; color: Color random).

              cell := (LayoutMorph newRow ::  morphExtent: 100 at 100;
                 color: Color lightGray; layoutSpec: LayoutSpec 
keepMorphExtent).
              cell addMorph: cellContent
                 layoutSpec: (LayoutSpec fixedExtent: cellContentExtent).
         cell axisEdgeWeight: #center.
         cells add: cell].

     table cells: cells


But I guess this is not what you meant when you wrote earlier in the thread

"Should be easy to add quite easily vertical alignment preferences."

But my suggestion is to keep this current morph as a FlowLayoutMorph as 
is and for a table with aligned columns go for another Layout morph type 
and call that TableLayoutMorph.

A TableLayoutMorph which lets you define the column widths.
