Usando o nome da coluna como intervalo

Question

como faço para usar um nome de coluna como intervalo no VBA Eu uso o código abaixo (CTTO) para formatação condicional, porém indiquei manualmente o intervalo. Desta vez, preciso usar o nome da coluna, pois haverá várias tabelas às quais desejo aplicar a formatação condicional.

    'Definining the variables:
  Dim rng As Range
  Dim condition1 As FormatCondition, condition2 As FormatCondition, condition3 As FormatCondition


 'Fixing/Setting the range on which conditional formatting is to be desired
  Set rng = Range("M5", "M16")


  'To delete/clear any existing conditional formatting from the range
   rng.FormatConditions.Delete


  'Defining and setting the criteria for each conditional format
   Set condition1 = rng.FormatConditions.Add(xlCellValue, xlEqual, "=""""")
   Set condition2 = rng.FormatConditions.Add(xlCellValue, xlGreater, "=report2!$K$1")
   Set condition3 = rng.FormatConditions.Add(xlCellValue, xlLess, "=report2!$K$1")

   rng.FormatConditions(1).StopIfTrue = True
   rng.FormatConditions(1).SetFirstPriority
   rng.FormatConditions(2).StopIfTrue = False
   rng.FormatConditions(3).StopIfTrue = False

   'Defining and setting the format to be applied for each condition
   With condition2
    .Font.Color = -16383844
    .Font.Bold = True
    .Font.TintAndShade = 0
    .Interior.PatternColorIndex = xlAutomatic
    .Interior.Color = 13551615
    .Interior.TintAndShade = 0
   End With

   With condition3
    .Font.ThemeColor = xlThemeColorDark1
    .Font.Bold = True
    .Font.TintAndShade = 0
    .Interior.PatternColorIndex = xlAutomatic
    .Interior.ThemeColor = xlThemeColorAccent6
    .Interior.TintAndShade = -0.499984740745262
   End With
