uitable is a mechanism to work with excel worksheets.  Bug report #63388 can
be looked at as displaying different worksheets on 
a same uitable.  This report is about the appearance of a worksheet. 

Octave uitable syntax follows an older version of matlab uitable that matlab
still supports.  uitable columnwidth can be a cell array.  Octave uitable
columnwidth appears to have an undocumented lower bound near 30, which matlab
does not have. 30 is a fairly large width.

Please use the example below.  The columnwidth remains the same after the
specified width is below 30.  If you have matlab resource, you should find 1
is still a legal/accepted width in matlab.     
    
I would recommend that either the columnwidth follows the specified number or
this lower bound  (and its reasoning) is documented as an incompatibility.

fid=figure; 
h=uitable(fid,'units','normalized', ...
'Position',[ 0.1 0.15 0.9 0.6  ], ...
'data',{'1111111' '1' '22'}, ...
'ColumnWidth',{100,100 100}, 'tag', 'example');  

for ii=100:-10:10, 
set(h, 'ColumnWidth', { 100, ii, 100});
set(fid, 'name', num2str(ii)); pause; 
end
