This .NET class wraps the CellEdgeMasks ObjectARX enum. 

These values specify the cell edge of a table cell.

Public Enum CellEdgeMasks
  BottomMask = 4
  LeftMask = 8
  RightMask = 2
  TopMask = 1
End Enum

public enum CellEdgeMasks {
  BottomMask = 4,
  LeftMask = 8,
  RightMask = 2,
  TopMask = 1
}
