AutoCAD .NET :: Syntax For Setting A Table Cell Type To Blockcell

I have tried: 

Table.SetCellType(0, 0, TableCellType.BlockCell)

result:

Warning 1 'Public Overridable Sub SetCellType(row As Integer, col As Integer, type As Autodesk.AutoCAD.DatabaseServices.TableCellType)' is obsolete: 'Use Cell functionality instead.'

Then i tried:

Tbl.Cells(0, 0).CellType(TableCellType.BlockCell)

result:

Error 1 Property access must assign to the property or use its value.

Then I tried:

Table.Cells(0,0).CellType = TableCellType.BlockCell

result:

Error 1 Property 'CellType' is 'ReadOnly'.
