I am trying to create a table in an app which the user can add a text comment to. However, whenever I try to change the value of a cell, it displays NaN. I have changed the format of the column to 'char', so I am unsure what the issue is.A and B are random vectors of numbers

            C=find(app.B>0.9);
            L=length(C);
            for i=1:1:L;
            app.UITable.Data(i,1)=[i];
            end
            app.UITable.Data(:,2:3)=0
            app.UITable.ColumnFormat(:,2)=({'char'});
            app.UITable.ColumnFormat(:,3)=({'char'});
            app.UITable.ColumnEditable=[false true true];

Any help would be greatly appreciated!

B is a property within the app

I had a similar problem occur while working on my own app. Below is my code with how I solved the issue.

app.UITable.ColumnFormat = {'char','char','numeric','numeric'};

if strcmp(app.VehicleTypeListBox.Value,'(Custom Weight)')

app.UITable.Data{1,1} = 'Custom Weight';

elseif strcmp(app.VehicleTypeListBox.Value,'SUV')

app.UITable.Data{1,1} = 'SUV';

elseif strcmp(app.VehicleTypeListBox.Value,'Pickup Truck')

app.UITable.Data{1,1} = 'Pickup Truck';

else

app.UITable.Data{1,1} = 'Sedan';

end

if strcmp(app.BrakePadMaterialDropDown.Value,'Ceramic')

app.UITable.Data{1,2} = 'Ceramic';

elseif strcmp(app.BrakePadMaterialDropDown.Value,'Semi-Metallic')

app.UITable.Data{1,2} = 'Semi-Metallic';

else

app.UITable.Data{1,2} = 'NAO (Non-Asbestos Organic)';

end

app.UITable.Data{1,3} = num2str(app.InitialSpeedMPHEditField.Value);

app.UITable.Data{1,4} = num2str(distance);

The solution I used make the table read strings also prevented the table from directly reading numbers. However, it is a lot easier to convert numbers into words, than converiing words inti numbers. I strongly encourage paying attention to the curly brackets specifying where the data goes in the table. This will not work if you use parenthesis.
