private Map<String, Integer> getCombineCellData(Sheet sheet) {
        int combineCellNum = sheet.getNumMergedRegions();

            CellRangeAddress cell = sheet.getMergedRegion(i);
            int firstColumnNum = cell.getFirstColumn();
            int firstRow = cell.getFirstRow();
            if (firstColumnNum == 3 && firstRow == 0) {
                Map<String, Integer> result = new HashMap<>();
                result.put("firstIndex", firstColumnNum);
                result.put("lastIndex", cell.getLastColumn());
                return result;
            }
