hi…
i know that for Edit a cell we can click or doubleclick on the cell and change the cell’s value (it’s easy)
but …
i want create a button that when we click on it automatically change some cell’s value … i found no function for it …
there is some function like …
setRowTextStyle ();
setRowTextBold ();
setRowTextNormal ();
but these function’s only can change the style of cell … i need a function that change(update) value of cell
also there is another value like …
setValue();
but there is no example and i can not use it
please make an example that what shoud i do.
I hope you understand that what is my probleme …!!! 
thank’s.
