I have seent hat its possible for a uitable to fill the square its created in using guide.

t=handles.uitable1;
% Set width and height
t.Position(3) = t.Extent(3)
t.Position(4) = t.Extent(4)

I also see that t has the following properties:

t =

Table (uitable1) with properties:
                Data: [3x5 double]
         ColumnWidth: {'auto'  'auto'  'auto'  'auto'}
      ColumnEditable: [0 0 0 0]
    CellEditCallback: ''
            Position: [0.0279 0.0418 1.0354 0.3769]
               Units: 'normalized'

Is it possible to set the column widths individually, for example I wanted 1st column to be a certain size and I thought

t.ColumnWidth(1)=20

might work but it doesnt.

Yes, it can be a cell array with numbers and 'auto' interleaved.

web(fullfile(docroot, 'matlab/ref/uitable-properties.html'))

Looks like you need to index into a cell for your example:

t.ColumnWidth{1} = 20

Note the curly {} for indexing into the cell.

Thankyou. I also found that you can do this:

set (handles.uitable1,'ColumnWidth', {48,52,83,83})

The two commands are doing the same thing. set is the old way, dot notation is the new way starting in 14b. dot notation is faster and in my opinion cleaner.
