How can I Autofill a Cell in a Table?

I have placed a (3,1) table in a GUI and would like it to autofill the third cell with the same value the user added in the first cell. How can this be done?

Set the uitable CellEditCallback property to a routine that checks the Indices field of the eventdata structure, and if the indices are [1 1] then get() the Data property of the uitable, and copy the eventdata New Value property to element {3,1} of that and set() that as the new Data property.
