Checboxes in uitable checked by default when starting GUI

Dear community,

I´ve been trying to solve a apparent simple problem for several days now:

I created a GUI using GUIDE with an UITABLE. I added some data to the uitable with 4 columns. The last column is a checkbox with logicals.

Now everything works fine, but I want that the checkboxes are checked by default when the GUI is started and not unchecked, as it is the case now.

My input data for the table is a 73 x 3 cell:

 'String 1' 'String 2' [ 1.234]

The only thing I found is to use in the Createfunction and " true " the

set(hObject,'Data',...)

command, but I can´t manage to correctly complete the command, so that the checkboxes are displayed as being checked. I would be utmost grateful for every help.

newdatacell = [existing_data_cell, repmat({true},size(existing_data_cell,1),1)];
set(handles.uitable1, 'Data', newdatacell);

That is, the 4th column needs to be initialized to a non-zero value in order for the 4th column to show up as checked.
