GUI 'uitable' with option to add rows using push button

I want to create an editable gui table which has a fixed number of columns (17) but variable number of rows (intially all entries should be zero) where new rows of zeros can be added using a push button. I want a user to be able to edit the entries in the table and then for these to be converted into a matrix. Any help would be greatly appreciated!

So far...

% --- Executes just before DB_table is made visible.
function DB_table_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% varargin   command line arguments to DB_table (see VARARGIN)

% Choose default command line output for DB_table
handles.output = hObject;

% Update handles structure
guidata(hObject, handles);

% UIWAIT makes DB_table wait for user response (see UIRESUME)
% uiwait(handles.figure1);

% --- Outputs from this function are returned to the command line.
function varargout = DB_table_OutputFcn(hObject, eventdata, handles) 
% varargout  cell array for returning output args (see VARARGOUT);
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Get default command line output from handles structure
varargout{1} = handles.output;

% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% --- Executes when entered data in editable cell(s) in uitable1.
function uitable1_CellEditCallback(hObject, eventdata, handles)
% hObject    handle to uitable1 (see GCBO)
% eventdata  structure with the following fields (see UITABLE)
%  Indices: row and column indices of the cell(s) edited
%  PreviousData: previous data for the cell(s) edited
%  EditData: string(s) entered by the user
%  NewData: EditData or its converted form set on the Data property. Empty if Data was not changed
%  Error: error string when failed to convert EditData to appropriate value for Data
% handles    structure with handles and user data (see GUIDATA)

Add button to your code of this form: handles.uitable is the handle to your uitable.

% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

data = get(handles.uitable, 'data');
data(end+1,:) = 0;
set(handles.uitable,'data',data)

Thanks for replying! But I get an error of the form

Conversion to cell from double is not possible.

Error in DB_table>pushbutton1_Callback (line 83) data(end+1,:) = 0;

and I'm not sure how to fix that.

Also any suggestions on how to convert the table entries into a matrix?

No need sorted it out. Thanks a lot!

[Z Chen]

how did you sort it out?

he puted this

data(end+1,:)={0};
