            // 得到一个sheet中有多少个合并单元格
            Integer sheetMergeCount = sheet.getNumMergedRegions();
            for (Integer i = 0; i < sheetMergeCount; i++) {
                // 获取合并后的单元格
                CellRangeAddress range = sheet.getMergedRegion(i);
                String cellValue = itemList.get(range.getFirstRow()).get(range.getFirstColumn());
                for (Integer mRowIndex = range.getFirstRow(); mRowIndex <= range.getLastRow(); mRowIndex++) {
                    for (Integer mColumnIndex = range.getFirstColumn(); mColumnIndex <= range.getLastColumn(); mColumnIndex++) {
                        itemList.get(mRowIndex).set(mColumnIndex, cellValue);
                    }
                }
