I do not understand why SetCellColor does not work.

I created a test code:

var rve: TCustomRichViewEdit;

    item: TCustomRVItemInfo;

    table: TRVTableItemInfo;

begin

  if RichViewEdit1.GetCurrentItemEx(TRVTableItemInfo, rve, item) then begin

    table := item as TRVTableItemInfo;

    rve.BeginUndoGroup(rvutModifyItem);

    table.SetCellColor(clRed, 0, 0);

    rve.Change;

    rve.Invalidate;

    rve.TopLevelEditor.Invalidate;

  end;

end;

and it works as expected

(this is a typical code for table editing operations;

SetUndoGroupMode(true)...SetUndoGroupMode(false) is not necessary because

there is only one operation here;

BeginItemModify...EndItemModify is not necessary because this operations

does not change table size, so Invalidate is used instead).

Unlike direct assignment to Cell.Color, the operation above can be undone by

user.

Ok, at least this problem is solved.
