为 React 网格应用程序配备 PDF 导出功能

7月 15, 2024
在保留其原始布局和格式的同时，通过直接从您的 React 应用程序将其导出为 PDF，轻松分发和查看网格数据。

Exporting a data grid to PDF captures the grid layout, including columns, rows, and formatting, and transforms it into a universally accessible and easily shareable document. The export creates a static file, retaining the original grid layout and formatting, that can be easily distributed and viewed consistently across different platforms and on any device with a PDF reader. Additionally, PDFs provide a secure format for preserving data integrity and can be protected against unauthorized editing, making them ideal for official documentation and archiving purposes. This functionality enhances collaboration and data dissemination efficiency by simplifying the sharing and printing processes while maintaining the original data structure and presentation.

Several React grid components allow you to export to PDF, including:

  • DevExtreme HTML5 JavaScript Data Grid (part of DevExtreme Complete by DevExpress) enables users to export data grids to PDF in React, preserving layout and formatting.
  • KendoReact Data Grid (part of KendoReact by Telerik) offers React applications seamless PDF export functionality, retaining the structure and design for easy distribution.
  • BestReactGrid facilitates grid data export to PDF format in React applications, maintaining the original layout and style for professional data presentation and collaboration.
  • Ignite UI React Grid (part of Infragistics Ignite UI) streamlines the export of data grids to PDF, ensuring consistent representation of data for secure and accessible sharing.
