javafx 表格 内容居中 java excel垂直居中

首先导jar包

<dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>easyexcel</artifactId>
            <version>2.1.4</version>
        </dependency

导出功能实体类

controller层

        //内容样式策略
        WriteCellStyle writeCellStyle = new WriteCellStyle();

        EasyExcel.write(response.getOutputStream(),Plan.class)//Plan为实体类模板

                .excelType(ExcelTypeEnum.XLS).head(Plan.class)

                //设置拦截器样式

自定义拦截器

public class MonthSheetWriteHandler implements SheetWriteHandler {
        //设置xls样式表拦截器
    @Override
    public void beforeSheetCreate(WriteWorkbookHolder writeWorkbookHolder, WriteSheetHolder writeSheetHolder) {

    }

    @Override
    public void afterSheetCreate(WriteWorkbookHolder writeWorkbookHolder, WriteSheetHolder writeSheetHolder) {
        SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd");
        String nowDate = df.format(new Date());
        String[] split = nowDate.split("-");
        Workbook workbook = writeWorkbookHolder.getWorkbook();
        Sheet sheet = writeSheetHolder.getSheet();
        Row row1 = sheet.createRow(0);
        row1.setHeight((short) 500);
        //设置标题
        sheet.addMergedRegionUnsafe(new CellRangeAddress(0, 0, 0, 12));
        Row row2 = sheet.createRow(0);
        row2.setHeight((short) 800);
        Cell cell1 = row2.createCell(0);
        cell1.setCellValue("郭家湾专用线" + split[0] +"年"+split[1]+ "月份发运计划提报单");
        sheet.addMergedRegionUnsafe(new CellRangeAddress(1, 1, 11, 12));
        Row row = sheet.createRow(1);
        String yMd= split[0]+"年"+ split[1]+ "月"+ split[2]+"日";
        row.createCell(11).setCellValue(yMd);
        CellStyle cellStyle = workbook.createCellStyle();
        cellStyle.setVerticalAlignment(VerticalAlignment.CENTER);
        cellStyle.setAlignment(HorizontalAlignment.CENTER);
        Font font = workbook.createFont();
        font.setBold(true);
        font.setFontHeight((short) 400);
        cellStyle.setFont(font);
        cell1.setCellStyle(cellStyle);
      sheet.addMergedRegionUnsafe(new CellRangeAddress(9, 9, 8, 12));
        Row row5 = sheet.createRow(9);
        row5.createCell(0).setCellValue("填表人：    日期："+yMd);
        row5.createCell(8).setCellValue("接收人：      日期：       年   月  日");
    }

效果：
