XSSFWorkbook 标题行换行
时间: 2024-01-12 12:55:28 浏览: 83
在使用XSSFWorkbook生成Excel文件时,如果需要在标题行换行,可以使用setWrapText(true)方法来设置单元格内容强制换行。具体实现如下:
1. 创建Workbook对象:
Workbook wb = new XSSFWorkbook();
2. 创建CellStyle对象并设置强制换行:
CellStyle cellStyle = wb.createCellStyle();
cellStyle.setWrapText(true);
3. 设置标题行内容,使用\r\n进行换行:
String str = "Hello" + "\r\n" + "World";
4. 创建单元格,并将设置好的样式和内容应用于单元格:
Cell cell = sheet.createRow(0).createCell(0);
cell.setCellStyle(cellStyle);
cell.setCellValue(wb.getCreationHelper().createRichTextString(str));
5. 最后保存文件:
try (OutputStream fileOut = new FileOutputStream(file)) {
wb.write(fileOut);
} catch (IOException e) {
throw new RuntimeException(e);
} finally {
wb.close();
}
通过以上步骤,即可在XSSFWorkbook的标题行实现换行效果。引用中的代码片段展示了如何使用XSSFWorkbook来实现标题行换行,引用中的代码片段展示了如何在XSSFWorkbook中设置单元格内容的强制换行样式。引用中的代码片段展示了如何在XSSFWorkbook中合并单元格,但与标题行换行无直接关系。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
