How can I edit cells with string values in a UITABLE?

I am trying to be able to edit a uitable, by means of using CellEditCallBack. However, even though I pretty much got the hang of it, I am finding trouble editing a cell containing a string, i.e., i want to input a value on the table that is actually not a number, but a string.

Is this possible? If so, how exactly does one get the CellEditCallBack only to work once the cell has been fully edited?

Also, why is it when I use get(hObject,'data') the result i get is NaN for the said string cell I am trying to edit?

The NaN may occur because the format for that column is numeric. That could be because you entered a numeric value for the property Data. You should enter a character value when you set up the table, e.g., for a 1-column table,

hObject = uitable('Data',{'whatever'});

If you later enter a numeric value, it will be converted to a string. If you don't want to specify an initial string, you could assign the column an empty string ('').
