How to allow user to modify data in a table in GUI?

I have a table and two pushbuttons in GUI. When I click the first button it displays the table. And when I press the second one it displays another table which was created by using the data in the fisrt table. I can allow user to modify the data in the fisrt table. However when I try to display the second table it displays the same result before the modifications were made.

Example:

t1: var1 var2 var3

       0    1    3
       1    3    2

t2: var1
     2
     3

I modify the table as:

t1: var1 var2 var3
   2    1    1
   3    0    1

but the table2 remans the same:

t2: var1
   2
   3

I have the following piece of code:

handles.data=[handles.C{1} handles.nums];

handles.f = figure;

handles.t = uitable(handles.f,'ColumnEditable', [true,true,true,true]);

handles.t.Data=handles.data;

Billie - please show more of your code especially that which updates the table. The code that you have shown seems to indicate that you are creating a new figure with one table, but it isn't clear how or where it is used.

[Billie Jean]

handles.fileName = uigetfile;
handles.fid=fopen(handles.fileName);
handles.C=textscan(handles.fid, '%s %f %f %f');
handles.nums=num2cell([handles.C{2}, handles.C{3}, handles.C{4}]);
handles.data=[handles.C{1} handles.nums];
handles.f = figure;
handles.t = uitable(handles.f,'ColumnEditable', [true,true,true,true],'Data',handles.data);
guidata(hObject,handles);

and after the rest of the code I need modified data on the table. But when I tried use the data in the table it is making the operation with the initail data that I took from txt file. I do not update the table. I let users to update the table by double clicking on the numbers on the figure and enter the new values.

Please show the bit about creating the second table and the bit about displaying it.

function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)
handles.fileName = uigetfile;
handles.fid=fopen(handles.fileName);
handles.C=textscan(handles.fid, '%s %f %f %f');
handles.nums=num2cell([handles.C{2}, handles.C{3}, handles.C{4}]);
handles.data=[handles.C{1} handles.nums];
handles.f = figure;
handles.t = uitable(handles.f,'ColumnEditable', [true,true,true,true],'Data',handles.data);
handles.cellArray = get(handles.t, 'Data');
guidata(hObject,handles);

function pushbutton2_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton2 (see GCBO)
handles.nodeVoltages=circuit(handles.cellArray);
handles.ff=figure;
handles.t = uitable(handles.ff);
handles.t.Data=handles.nodeVoltages;

circuit is a function that I wrote. It takes a cell array and gives an array as output.

That result is expected. Modifying one uitable never affects another uitable, not unless the two have had their contents linked together using linkprop(), or not unless there are callbacks set on the first table that tell it to update the second table as well.

[Billie Jean]

How can I employ linkprop here?

function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)
handles.fileName = uigetfile;
fid = fopen(handles.fileName);
C = textscan(fid, '%s %f %f %f');
nums = num2cell([C{2}, C{3}, C{4}]);
data = [handles.C{1} handles.nums];
handles.f = figure;
handles.t = uitable('Parent', handles.f, 'ColumnEditable', [true,true,true,true], 'Data', data);
guidata(hObject, handles);

function pushbutton2_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton2 (see GCBO)
cellArray = get(handles.t, 'Data');
nodeVoltages = circuit(handles.cellArray);
handles.ff = figure;
handles.t2 = uitable('Parent', handles.ff, 'Data', nodeVoltages );
guidata(hObject, handles);
