POI-tl 知识整理：整理3 -＞动态生成表格

本文主要是介绍POI-tl 知识整理：整理3 -＞动态生成表格，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1 表格行循环

（1）需要渲染的表格的模板

说明：{{goods}} 是个标准的标签，将 {{goods}} 置于循环行的上一行，循环行设置要循环的标签和内容，注意此时的标签应该使用 [] ，以此来区别poi-tl的默认标签语法。同理，{{labors}} 也置于循环行的上一行。

（2）定义两个实体类

@Data
public class Goods {private int count;private String name;private String desc;private int discount;private int tax;
}@Data
public class Labors {private String category;private int people;private int price;
}

（3）测试代码

    @Testpublic void autoGenerateTable1() throws Exception {// 数据Goods goods1 = new Goods();Goods goods2 = new Goods();Labors labors1 = new Labors();Labors labors2 = new Labors();goods1.setCount(2);goods1.setName("商品1");goods1.setDiscount(10);goods1.setDesc("商品1描述");goods1.setTax(5);goods2.setCount(4);goods2.setName("商品2");goods2.setDiscount(20);goods2.setDesc("商品2描述");goods2.setTax(10);List<Goods> goodsList = Arrays.asList(goods1, goods2);labors1.setPeople(3);labors1.setCategory("类别1");labors1.setPrice(100);labors2.setPeople(1);labors2.setCategory("类别2");labors2.setPrice(200);List<Labors> laborList = Arrays.asList(labors1, labors2);// 用行循环插件LoopRowTableRenderPolicy renderPolicy = new LoopRowTableRenderPolicy();ConfigureBuilder builder = Configure.builder();Configure configure = builder.bind("goods", renderPolicy).bind("labors", renderPolicy).build();XWPFTemplate template = XWPFTemplate.compile("D:\\Idea-projects\\POI_word\\templates_autoGenerateTable.docx",configure);Map<String, Object> map = new HashMap<>();map.put("goods", goodsList);map.put("labors", laborList);template.render(map);FileOutputStream fileOutputStream = new FileOutputStream("D:\\Idea-projects\\POI_word\\output_autoGenerateTable.docx");template.writeAndClose(fileOutputStream);template.close();}

（4）渲染结果

（5）测试代码详细解释

2 表格列循环

列循环跟行循环没有什么区别，就是将行循环插件换成了列循环插件

（1) 模板

（2）测试代码

    @Testpublic void autoGenerateTable2() throws Exception {// 数据Labors labors1 = new Labors();Labors labors2 = new Labors();labors1.setPeople(3);labors1.setCategory("类别1");labors1.setPrice(100);labors2.setPeople(1);labors2.setCategory("类别2");labors2.setPrice(200);List<Labors> laborList = Arrays.asList(labors1, labors2);// 用列循环插件LoopColumnTableRenderPolicy renderPolicy = new LoopColumnTableRenderPolicy();ConfigureBuilder builder = Configure.builder();Configure configure = builder.bind("labors", renderPolicy).build();XWPFTemplate template = XWPFTemplate.compile("D:\\Idea-projects\\POI_word\\templates_autoGenerateTableCol.docx",configure);Map<String, Object> map = new HashMap<>();map.put("labors", laborList);template.render(map);FileOutputStream fileOutputStream = new FileOutputStream("D:\\Idea-projects\\POI_word\\output_autoGenerateTableCol.docx");template.writeAndClose(fileOutputStream);template.close();}
