Bonjour,
Pour le principe, une proposition :
Option Explicit
Public Sub copyFormat()
Dim ws As Worksheet
Dim rng As Range
Dim vlg As Variant
Application.ScreenUpdating = False
Set ws = Worksheets("Feuil1")
vlg = Columns(1).ColumnWidth
Set rng = ws.Range("A1:A27")
rng.Copy
Cells(1, 3).PasteSpecial Paste:=xlPasteFormats
Columns(3).ColumnWidth = vlg
Set ws = Nothing: Set rng = Nothing
End Sub
