                    // 图片插入坐标  
                     anchor.setCol1(readColNo);  
                     anchor.setRow1(tr_idx);
                     anchor.setCol2(readColNo + colspan - 1);
                     anchor.setRow2(rowspan + tr_idx - 1);
                     // 插入图片  
                     HSSFPicture pict = drawingPatriarch.createPicture(anchor, pictureIdx);  
                     pict.resize(); 
                 }catch(Exception e){
                     throw e;
                 }finally{
                     if(is != null){
                         is.close();
                         is = null;
                     }
                 }
