Ext.grid.column.number no 'renderer' in Architect 3.1

Is RENDERER for Ext.grid.column.number removed in the Config list of Architect 3.1?

I need this to add style to the number column when certain conditions are met by other columns in the same grid panel.

If this is intentionally removed (I've seen some thread regarding this...), then what's the best way to do my scenario in Architect 3.1?
