JAVA poi 合並單元格

完整幫助代碼：JAVA poi 幫助類

            // 得到一個sheet中有多少個合並單元格
            Integer sheetMergeCount = sheet.getNumMergedRegions();
            for (Integer i = 0; i < sheetMergeCount; i++) {
                // 獲取合並后的單元格
                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);
                    }
                }
            }
