How to get texts in table cells

Hi,

   Does anyone know how to get texts in table cells?

   Currently I'm getting texts of an indd file using,

        InterfacePtr<IHierarchy> columnitemHierarchy(textFrameitemHierarchy->QueryChild(frameitemChildcount));

       InterfacePtr<ITextFrameColumn> textFramecolumn(columnitemHierarchy ,UseDefaultIID());

       IFrameList* frameList = textFramecolumn->QueryFrameList();

       ITextModel* textModel = frameList->QueryTextModel();

        But this way I can't get texts in some tables & texts in a kind of tables can be read. So I can' understand what the issue is.

Thanks
