How to chgthe colour or font style of a Custom Grp Format

I want to be able to change the background colour or text colour or text style on a Custom Grp Format depending on some conditions for the individual rows within the group. Please can you tell me how I would do that.

Thanks

Thinking about this further I actually would want to change the colour or font style for ANY column in the Group Header Row. So my adjusted questions are :

  1. How do I access a particular Group Header Row’s cell?

  2. Can I use the formatting commands on Group Header Row just like I do with a normal row?

Thanks

Unfortunately it’s not available to customize a style of a group row

  1. How do I access a particular Group Header Row’s cell?
    Unfortunately such feature is not supported

  2. Can I use the formatting commands on Group Header Row just like I do with a normal row?
    Stat-based values are rendered using the same exCell as the related column. This allows to use setNumberFormat() against them (when the source column is of ron|edn type).
