Setting attributes per cell in treeview (list store)

[Mike Martin <redtux1 gmail com>]

Hi I have a simple tree view based on a list store

What is the best way to set attributes per row/column is for a specific
cell not for a row or column?

Basically it is used to set various options and some cells are not used, so
I want them to be non-activatable /selectable to prevent any confusion

It a 12 by two table so performance not an issue

Is setting a cell_data_func based on row the best way to go? Or is there a
better way to achieve what I want?

Thanks

Mike
