Warning: Table data is not editable at this location. uitable turn from array type into to single element (1x1)

I am having a working GUI only on the first run, however After updating the table once, the uitable type turn from an array into a single (1x1) element. and this obstructs data feeding for another run throwing me an error "Warning: Table data is not editable at this location" in every attempt.

THE PROBLEM IS DUE TO A LINE x = get(handles.uitable1,'data') What type of table property should I update after the first run so that it works well successively?

I just want to avoid using two tables.

Thank you for your time

function varargout = TABLE3(varargin)

gui_Singleton = 1;
gui_State = struct('gui_Name',       mfilename, ...
                   'gui_Singleton',  gui_Singleton, ...
                   'gui_OpeningFcn', @TABLE3_OpeningFcn, ...
                   'gui_OutputFcn',  @TABLE3_OutputFcn, ...
                   'gui_LayoutFcn',  [] , ...
                   'gui_Callback',   []);
if nargin && ischar(varargin{1})
    gui_State.gui_Callback = str2func(varargin{1});
end

    [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});

What is the expected size of your table? What values are you entering into it?

Hello Enkuneh,

As per my understanding you want to access the data from the table, but in doing so you are currently getting error. The reason for the error "Table data is not editable at this location" is that get(handles.uitable1,'data') returns a single scalar value instead of a cell or double array.

After updating the data in the table using set(handles.uitable1,'Data',Data), you can retrieve the updated data as a double array using Data = cell2mat(get(handles.uitable1,'data')).

Here's the modified code that you should use in place of the line throwing error:

x = cell2mat(get(handles.uitable1,'data')); 

By using cell2mat, we convert the result of get(handles.uitable1, 'data') to a double array, even if it has only one element. This allows you to access and modify the array elements directly.

If you do not want to use two tables, you can modify your callback function to store the original table data in a separate variable at the beginning of the function. Then, you can update the original data in this variable and use it to update the table without having to retrieve it from the table itself.

For more information on cell2mat, please refer

Hope it helps!
