the class WriteLargeTest method test.

@Test
public void test() throws Exception {
    // 方法2 如果写到不同的sheet 同一个对象
    String fileName = TestFileUtil.getPath() + "large" + System.currentTimeMillis() + ".xlsx";
    // 头的策略
    WriteCellStyle headWriteCellStyle = new WriteCellStyle();
    // 背景设置为红色
    headWriteCellStyle.setFillForegroundColor(IndexedColors.RED.getIndex());
    WriteFont headWriteFont = new WriteFont();
    headWriteFont.setFontHeightInPoints((short) 20);
    headWriteCellStyle.setWriteFont(headWriteFont);
    // 内容的策略
    WriteCellStyle contentWriteCellStyle = new WriteCellStyle();
    // 这里需要指定 FillPatternType 为FillPatternType.SOLID_FOREGROUND 不然无法显示背景颜色.头默认了 FillPatternType所以可以不指定
    contentWriteCellStyle.setFillPatternType(FillPatternType.SOLID_FOREGROUND);
    // 背景绿色
    contentWriteCellStyle.setFillForegroundColor(IndexedColors.GREEN.getIndex());
    WriteFont contentWriteFont = new WriteFont();
    // 字体大小
    contentWriteFont.setFontHeightInPoints((short) 20);
    contentWriteCellStyle.setWriteFont(contentWriteFont);
    // 这个策略是 头是头的样式 内容是内容的样式 其他的策略可以自己实现
    HorizontalCellStyleStrategy horizontalCellStyleStrategy = new HorizontalCellStyleStrategy(headWriteCellStyle, contentWriteCellStyle);

Example 57 with ExcelWriter

use of com.alibaba.excel.ExcelWriter in project easyexcel by alibaba.

the class Wirte method tableWrite.

@Test
public void tableWrite() {
    String fileName = TestFileUtil.getPath() + "tableWrite" + System.currentTimeMillis() + ".xlsx";
    // 这里直接写多个table的案例了，如果只有一个 也可以直一行代码搞定，参照其他案例
    // 这里 需要指定写用哪个class去写
    ExcelWriter excelWriter = EasyExcel.write(fileName).build();
    // 把sheet设置为不需要头 不然会输出sheet的头 这样看起来第一个table 就有2个头了
    WriteSheet writeSheet = EasyExcel.writerSheet("模板").build();
    // 这里必须指定需要头，table 会继承sheet的配置，sheet配置了不需要，table 默认也是不需要
    WriteTable writeTable0 = EasyExcel.writerTable(0).head(DemoData1.class).build();
    // 第一次写入会创建头
    excelWriter.write(data(), writeSheet, writeTable0);
    // 第二次写如也会创建头，然后在第一次的后面写入数据
    // / 千万别忘记close 会帮忙关闭流
    excelWriter.finish();
