Normally, empty cells have a single empty text items.

Code: Select all

function IsEmpyCell(Cell: TRVTableCellData): Boolean;
var RVData: TCustomRVData;
begin
  RVData := Cell.GetRVData;
  Result := (RVData.ItemCount = 0) or
    ((RVData.ItemCount = 1) and (RVData.GetItemStyle(0) >= 0) and
    (RVData.GetItemText(0)=''));
end;

The data in cells[0,0] is the way it is.

table.Cells[0,0].InsertRVFFromStream(Stream , 0, Dummy1 ,dummy2,dummy3 ,False, nil,nil);

IsEmpyCell Return incorrect¡£

Are you sure that the cell is not being edited at the moment of insertion?
Try
table.Cells[0,0].GetRVData.InsertRVFFromStream(...)

I'm sorry, I was wrong.

rveMain.LoadRTF(111.rtf)

111.rtf -- this file contains a table.

I received your email.
Your RTF file does not have empty cells.
Any cell contain something, for example space characters.
You can see them, if you click in "Show non-printing characters" in MS Word or in our ActionTest project.
