>After re-reading my formula I see, that mine is incorrect. Why I use GridLineWidth*2? Should it be (.ColumnCount-1)*GridLineWidth instead? May be that's why I added some numbers like + 10 here...

I discovered that GridLineWidth and GridLines (On or Off) don't affect the width of the Grid. (That caught me offguard).

I am curious as to what the 3 is needed for. Assuming that there is 1 pixel to the right of each column (therefore needing .ColumnCount), then 1 of the 3 would probably be the pixel to the left of Column1. But what are the other 2 for? My guess would be the borders (left & right).
