PDF 导出基础示例

概述本 Demo 展示了 SpreadJS 导出 PDF 的基本功能。Demo 中创建了一个家庭业务成本分析表，包含年度数据表格和饼图迷你图，并设置了打印选项（页眉、页脚、网格线、边框），点击按钮即可将工作表导出为 PDF 文件。实现思路引入必要的插件：打印插件（gc.spread.sheets.print.min.js）和 PDF 插件（gc.spread.sheets.pdf.min.js）初始化工作簿并创建数据表格，设置单元格样式和公式添加饼图迷你图展示数据占比配置打印信息：设置页眉、页脚、边框和网格线绑定按钮事件，调用 savePDF 方法导出 PDF 代码解析引入插件导出 PDF 需要先引入打印插件和 PDF 插件，且打印插件必须先加载：设置打印信息这段代码配置了打印选项：showBorder 显示边框，showGridLine 显示网格线，headerCenter 设置页眉中间文本，footerCenter 使用特殊格式 &P/&N 显示当前页码和总页数。导出 PDF 调用 savePDF 方法导出 PDF：第一个参数是成功回调函数，接收导出的 blob 对象；第二个参数是错误回调函数；第三个参数设置 PDF 文档属性（标题、作者、主题等）。创建饼图迷你图使用 PIESPARKLINE 公式创建饼图迷你图，第一个参数是数据范围，后续参数指定各扇形的颜色。运行效果页面显示一个家庭业务成本分析表，包含 2018-2022 年的各项成本数据表格下方显示一个饼图迷你图，直观展示各项成本的占比点击"导出 PDF"按钮，浏览器会下载名为 download.pdf 的文件导出的 PDF 包含完整的数据表格、饼图迷你图、页眉（Family Business Costs）和页脚（页码/总页数） API 参考 savePDF 方法 successCallback: 成功回调函数，参数为 blob 对象 errorCallback: 错误回调函数，参数为错误信息 options: PDF 文档选项（可选） options.title: 文档标题 options.author: 文档作者 options.subject: 文档主题 options.keywords: 文档关键字 options.creator: 创建者应用名称 sheetIndex: 指定导出的工作表索引（可选），不设置则导出所有可见工作表 printInfo 方法获取工作表的打印信息对象，可设置： showBorder(boolean): 是否显示边框 showGridLine(boolean): 是否显示网格线 headerCenter(text): 设置页眉中间内容 headerLeft(text): 设置页眉左侧内容 footerCenter(text): 设置页脚中间内容页眉页脚支持的特殊格式： &P: 当前页码 &N: 总页数 &D: 当前日期 &T: 当前时间 &G: 图片占位符
