4、开始使用

var fileName = $("#docP_article .doc-article-title").text().trim();

5、效果图

注：“jquery.min.js、 FileSaver.js、 jquery.wordexport.js”的引用顺序必须是这样

2、依赖于 jquery.table.excel.js 插件

3、开始使用
jQuery 之 TABLE 生成 Excel 文档
该行不会被输出到excel中
该行不会被输出到excel中
这一行会被导出到excel中
这一行会被导出到excel中
单元格1-1
单元格1-2
单元格2-1

单元格3-1
单元格3-2
