Thanks, I figured there is no high-level way to do it. What I'm doing now, is using the Cell Selection Callback to find the index of the cell. Then I set the index to a handle.
As shown below:

function inputTable_CellSelectionCallback(source, eventdata)
handles=guidata(source);
handles.currentCell=eventdata.Indices
guidata(gcf,handles)
end

Then I use this index in the KeyPressFcn to manually store the data on keypress.

function inputTable_KeyPressFcn(source, eventdata)
handles=guidata(gcf);
Indices=handles.currentCell;
data=get(source,'Data');
data{Indices(1),Indices(2)}=str2double(eventdata.Key)
set(handles.inputTable,'Data',data);
end

This seems to work if only one number is inputed. However if we go to double digits, the last one gets removed. I could concatenate what's already in the cell with the new key, but as you mentioned, backspace/arrows etc. will also have to be manually programmed. I don't think other coders will like that. Addtionally, the set command causes the cell to lose focus, making cellselection give an error.

I guess I'll switch back to edit boxes or something. Thanks for the help though. Now I know it can't be done.

This is an intolerable snide on Java components :-)
Of course it can be done - you just need to get the relevant Java component (for example, using the FindJObj utility on the File Exchange) and then set its FocusLostCallback to trigger an editting-stop action:

mtable = uitable(...);
jscroll = findjobj(mtable);
jtable = jscroll.getViewport.getComponent(0);
hjtable = handle(jtable,'CallbackProperties');
set(hjtable, 'FocusLostCallback', @myCallbackFunc);

function myCallbackFunc(jtable,eventdata)
component = jtable.getEditorComponent;
if ~isempty(component)
event = javax.swing.event.ChangeEvent(component);
jtable.editingStopped(event);
end
end

Or an even simpler hack (see related: http://bugs.sun.com/bugdatabase/view_bug.do;:WuuT?bug_id=4709394 ):
jtable.putClientProperty('terminateEditOnFocusLost', true);

jscroll = findjobj(t);
jtable = jscroll.getViewport.getComponent(0);
The value is stored in get(jtable.getEditorComponent,'text'). when hit the button I use the stored value to replace the value read from data=get(table,'Data').

> I'm making a GUI that takes in input via a table. As the user, you would add data then click start to run the algorithm using the data from the table. My issue is that the Data in a cell is not updated until the user actually moves away from the cell. Is there a way to have the data update upon the value being changed. The table's callback also only runs once the user have moved away from the cell.
