Hello!

I want to create a table with the numbers of rows and columns previously requested to the user.

(the number of columns is given by app.colonna and the number of rows is given by app.slice)

In every cell I need a checkbox.

How can i create this table?

fig = uifigure;

tdata = table([false; false; false]);

uit = uitable(fig,'Data',tdata);

uit.Position(3) = 130;

uit.RowName = 'numbered';

You can create properties and set the values using following code

properties (Access = private) 
        Property % Description 
        colonna=3; %columns 
        slice=2;  %rows 
    end 

You can use following code to create table with the given number of rows and columns and with check boxes in each row.

methods (Access = private)  
        % Code that executes after component creation 
        function startupFcn(app) 
             
            fig = uifigure; 
            tdata = table('Size',[app.slice, app.colonna],'VariableTypes',["logical","string","string"]);  % use “logical” to get checkbox in first column 
            uit = uitable(fig,'Data',tdata,'ColumnEditable',[true false false]); %  columns can be editable if ColumnEditable is true  
            uit.Position(3) = 130; 
            uit.RowName = 'numbered'; 
        end 
    end
