horizontalSeparatorSkin and AdvancedDataGrid

[fu-meng]

Hi -

I'm trying to put a 5px space inbetween AdvancedDataGrid rows, but I don't want any space between the AdvancedDataGrid and its renderer (another DataGrid).

I tried creating a spacer gif and using that as the horizontalSeparatorSkin in the
outer AdvancedDataGrid but it puts a space not only between the rows but between the renderer as well.

Is there another way of accomplishing this?

Thanks for any tips.
