[alibaba/easyexcel]使用合并单元格后，线程卡死

   public class PackageInfoRowMergeStrategy implements CellWriteHandler {

    /**
     * 需要合并的行
     */

            return;
        }
        for(Integer num : mergeRowIndex){

            writeSheetHolder.getSheet().addMergedRegionUnsafe(cellRangeAddress);
        }
    }
}
