MATLAB: Help: Table cannot edit in a programmatic GUI

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
