Fit text in table cell

I asked this early, but maybe somebody find way how to do this

if (sub.GetTypeName2() == "GeneralTableFeature")

                    {

                        bool selected = sub.Select(false); //return true

                        GeneralTableFeature genTable = (GeneralTableFeature)model.ISelectionManager.GetSelectedObject6(1, -1);

                        model.ClearSelection2(true);

                        TableAnnotation ooo = (TableAnnotation)genTable.GetTableAnnotations()[0];

                        Annotation ann = ooo.GetAnnotation();

                        ann.Select(false); //return true

                        var isRun = swApp.RunCommand((int)swCommands_e.swCommands_FitText, ""); //return true

                        model.ClearSelection2(true);

                    }//

But method do nothing. All cells wich have extended text - stay with extended text.

Maybe this problem has a different solution?
