您好!关于您的问题,可以使用POI类库来读取Excel,并可以使用CellStyle类来设置单元格的合并方式。具体操作可以参考以下代码:
```
public void mergeCells(String filepath) {
try {
FileInputStream fis = new FileInputStream(filepath);
Workbook workbook = new HSSFWorkbook(fis);
Sheet sheet = workbook.getSheetAt(0);
CellRangeAddress region = new CellRangeAddress(0, 2, 0, 0);
Cell cell = sheet.getRow(0).getCell(0);
cell.setCellValue("Merged Cell");
CellStyle style = workbook.createCellStyle();
style.setAlignment(HorizontalAlignment.CENTER);
style.setVerticalAlignment(VerticalAlignment.CENTER);
cell.setCellStyle(style);
sheet.addMergedRegion(region);
FileOutputStream fos = new FileOutputStream(filepath);
workbook.write(fos);
fos.close();
} catch (Exception e) {
e.printStackTrace();
}
}
```
我已经回答了您的问题,还需要帮助吗?
