Do you mean you want a border around the range?
And this border to have rounded corners?
From Drawing Toolbar select rounded rectangle from Basic Shapes.
Place it over your range and set its properties to Transparent.
Or use this macro after selecting the range of cells.
Sub RoundRectangle()
Dim x, y As Single, area As Range
For Each area In Selection.Areas
With area
x = .Height * 0#
y = .Width * 0#
ActiveSheet.Rectangles.Add Top:=.Top - x, Left:=.Left - y, _
Height:=.Height + 1 * x, Width:=.Width + 1 * y
End With
With ActiveSheet.Rectangles(ActiveSheet.Rectangles.Count)
.Interior.ColorIndex = xlNone
.ShapeRange.AutoShapeType = msoShapeRoundedRectangle
End With
Next area
End Sub
