Help: Table cannot edit in a programmatic GUI?

Hi everybody,

Could someone tell me what's wrong with my code? I created a figure with a table in GUIDE and converted it to programmatic by Fig2m (by Thomas Montagnon). Then when I run the figure, the table was shown but cannot edit although I set it editable in GUIDE.

The command window showed 'Warning: Table data is not editable at this location.'

The code:

    % --- FIGURE -------------------------------------
    handles.figure1 = figure( ...
      'Tag', 'figure1', ...
      'Units', 'characters', ...
      'Position', [102.8 24.2307692307692 114 33], ...
      'Name', 'untitled1', ...
      'MenuBar', 'none', ...
      'NumberTitle', 'off', ...
      'Color', [0.941 0.941 0.941]);

    % --- UITABLE -------------------------------------
    handles.uitable1 = uitable( ...
      'Parent', handles.figure1, ...
      'Tag', 'uitable1', ...
      'UserData', zeros(1,0), ...
      'Units', 'characters', ...
      'Position', [12.2 8 36.8 21], ...
      'BackgroundColor', [1 1 1;0.961 0.961 0.961], ...
      'ColumnEditable', [true,true], ...
      'ColumnFormat', {'char' 'char' }, ...
      'ColumnName', {'1','2'}, ...
      'ColumnWidth', {'auto','auto'}, ...
      'RowName', {'1','2','3','4'});

Thank you.

Hi,

You need to initialize the type the Data parameter. by default, Matlab consider it is a double. But you want to put strings in your table. So just specify an cell with empty string when creating the uitable.

    % --- FIGURE -------------------------------------
  handles.figure1 = figure( ...
      'Tag', 'figure1', ...
      'Units', 'characters', ...
      'Position', [102.8 24.2307692307692 114 33], ...
      'Name', 'untitled1', ...
      'MenuBar', 'none', ...
      'NumberTitle', 'off', ...
      'Color', [0.941 0.941 0.941]);
  % --- UITABLE -------------------------------------
  % Initialize empty string for components of the Data
  Data=cell(4,2);
  for i = 1:numel(Data)
      Data{i} = '';
  end

handles.uitable1 = uitable( ...
    'Parent', handles.figure1, ...
    'Tag', 'uitable1', ...
    'UserData', zeros(1,0), ...
    'Units', 'characters', ...
    'Position', [12.2 8 36.8 21], ...
    'BackgroundColor', [1 1 1;0.961 0.961 0.961], ...
    'ColumnEditable', [true,true], ...
    'ColumnFormat', {'char','char' }, ...
    'ColumnName', {'1','2'}, ...
    'ColumnWidth', {'auto','auto'}, ...
    'RowName', {'1','2','3','4'},...
    'Data',Data); % add the "string" Data

Thank you so much.

My problem was solved. It's so simple. I even thought that MATLAB on my computer had a problem.

In my UI I want to make user defined rows (the no user will enter in EditText) with 3 columns, Then the data entered I want to do mathematical calculations on it. With above answer I was able to get table but don't know how to get the user entered data. The above answer was useful to me but only half part. Suggest some advise. Thanks in advance.
