This .NET class wraps the CellProperty ObjectARX enum. 

These values specify the cell properties.

Public Enum CellProperties
  Alignment = &H10
  AutoScale = &H100
  BackgroundColor = &H200
  ContentColor = &H20
  ContentLayout = &H4000
  DataFormat = 2
  DataType = 1
  FlowDirBtoT = &H10000
  Invalid = 0
  MarginBottom = &H2000
  MarginHorzSpacing = &H20000
  MarginLeft = &H400
  MarginRight = &H1000
  MarginTop = &H800
  MarginVertSpacing = &H40000
  MergeAll = &H8000
  Rotation = 4
  Scale = 8
  TextHeight = &H80
  TextStyle = &H40
End Enum
