关于poi取消合并区域的方法-java

//主要用于原来的excel模板已经存在合并区域、再次合并会导致合并异常
private boolean removeMergedRegion(Sheet sheet, CellRangeAddress mergedRegionToRemove) {
        boolean removed = false;
        for (int i = 0; i < sheet.getNumMergedRegions(); i++) {
            CellRangeAddress mergedRegion = sheet.getMergedRegion(i);
            if (mergedRegionToRemove.equals(mergedRegion)) {
                sheet.removeMergedRegion(i);
                removed = true;
                break;
            }
        }
        return removed;
    }

经过测试可以使用，样例：

Sheet sheet = workbook.getSheetAt(sheetIndex);
removeMergedRegion(sheet,new CellRangeAddress(0,0,0,16));
