To insert a general table annotation programmatically into a solid model (part or assembly), one must use the InsertGeneralTableAnnotation method of the IModelDocExtension class. The table is inserted, but selecting the table, the scale is null, and the scale factor cannot be changed.

 By inserting the table manually, all works fine. 

 Is there any other solution than using the InsertGeneralTableAnnotation method?

Below is the code snippet

  table = NULL;
  if (ownerDoc->isDrawing ( ))
  {
     // Get the center point of the current sheet
     double h, w;
     long size;
     BSTR name;
     CComPtr sheet;
     CComPtr drawingDoc = CTools::toDrawing ( modelDoc );
     hr = drawingDoc->IGetCurrentSheet ( &sheet );
     hr = sheet->GetSize ( &w, &h, &size );
     hr = sheet->GetName ( &name );
     printfs ( L"Sheet Name : %s, h : %.3f w : %.3f\n", name, w, h );
     double htable = (type == TypeTable::DETAIL) ? (h / 2) : (2 * h / 3);
     hr = drawingDoc->InsertTableAnnotation2 ( VARIANT_FALSE, w/2, htable, 1,
                                               (wchar_t*)templateFile.c_str ( ), 10, 20, &table );
  }
  else
  {
     CComPtr ext;
     hr = modelDoc->get_Extension ( &ext );

     // get the 2D annotation view and select it
     CComPtr noteArea = CScanTools::retrieve2DAnnotationView ( ownerDoc->getModelDoc() );
     if (noteArea == NULL) return false;   // The 2D annotation view was not found
     noteArea->Select2 ( VARIANT_FALSE, 0, &ret );
     modelDoc->WindowRedraw ( );

     // Create the table
     table = NULL;
     hr = ext->InsertGeneralTableAnnotation ( VARIANT_FALSE, 0, 0, 1,
                                              (wchar_t*) templateFile.c_str ( ), 10, 20, &table );
     if (table != NULL)
     {
        hr = table->put_BorderLineWeight ( 0 );
        hr = table->put_GridLineWeight ( 0 );
     }
     modelDoc->WindowRedraw ( );
     modelDoc->ClearSelection2 ( VARIANT_TRUE );
     modelDoc->WindowRedraw ( );
  }

Then when editing the table, the scale of the table is zero and it cannot be changed
