完全なカスタマイズでテーブルのスタイリングが向上

8月 18, 2025
Froala Editor 4.6.0には、背景色、寸法、配置をカスタマイズするための直感的なコントロールを備えた高度なテーブルプロパティモーダルを追加

Froala Editor is a JavaScript-based WYSIWYG HTML editor that empowers developers to seamlessly integrate rich text editing functionalities into their applications. Despite its extensive feature set of over 100 options, Froala prioritizes user experience through a cleverly designed toolbar. Actions are categorized into four intuitive scopes, ensuring every feature is readily accessible while maintaining a clean and uncluttered interface. This balance of power and usability makes Froala Editor a versatile solution for a wide range of content creation scenarios.

The Froala Editor 4.6.0 update introduces a highly configurable Table Properties modal that brings detailed table customization into a single, accessible interface. Activated via the table toolbar, this modal lets users set background colors using a color picker that supports both RGB and hex values, applying changes uniformly across all cells. Table borders can now be precisely styled with user-defined color, thickness, and style options such as solid, dotted, dashed, and more. Users can also define table width and height in pixels or percentages, ensuring responsive layouts that adapt to various screen sizes. Alignment controls allow tables to be positioned left, center, or right within the content area. For enhanced readability, especially in data-intensive scenarios, alternating row colors can be toggled on or off to visually separate content. This update gives developers and content creators the granular control needed to create well-structured and visually consistent tables.

LAMBDA関数をセル選択に直接適用

8月 15, 2025
SpreadJS 18.2では、選択したセルに対してLAMBDA数式を実行し、1つのステップで置き換えるための新しい変換コマンドを追加

SpreadJS is a high-performance JavaScript spreadsheet and data presentation component designed for enterprise web applications. It enables developers to deliver Excel-like functionality directly within their web solutions, providing advanced features such as data binding, complex calculations, pivot tables, charts, and extensive formatting options. Fully compatible with modern JavaScript frameworks like React, Angular, and Vue, SpreadJS allows seamless integration and customization, empowering development teams to create interactive, data-driven user experiences without relying on external spreadsheet applications.

The SpreadJS 18.2 adds a new Transform command which enables you to apply LAMBDA functions directly to a selected range of cells and replace the original content with calculated results. This simplifies data transformations - whether mapping, filtering, or reshaping - into a clean, single-step process. With this feature, you can select any range and apply a custom LAMBDA formula - for example, converting units, adjusting values, or formatting entries - and have SpreadJS overwrite the selection with the computed results immediately. This removes manual steps like inserting formulas in separate cells, copying values, or pasting back as values. This feature integrates with SpreadJS’s existing LAMBDA capabilities to offer more interactive and efficient spreadsheet manipulation.

To see a full list of what's new in 18.2, see our release notes.

SpreadJS is licensed per developer and includes 1 Year Maintenance (major and minor version releases and unlimited support phone calls). SpreadJS requires an Annual or Perpetual Deployment License. The optional Add-ons are available at an additional cost, and require a SpreadJS license. See our SpreadJS licensing page for full details.

定義済みデータ範囲をVue.jsでエクスポート

8月 14, 2025
エクスポート選択機能が組み込まれたグリッドを使用すると、ユーザーはデータグリッド全体をエクスポートするのではなく、特定の行、列、またはセルを選択可能

Export selection in a data grid is the ability to export only a defined range, the specific rows, columns or cells that a user has actively selected, rather than the entire dataset. This selective approach is particularly valuable when working with large data sets, as it allows users to extract and share only the most relevant subset of information without additional filtering or manual deletion after export. By reducing the volume of unnecessary data in exported files, it improves efficiency, helps maintain focus on the intended content, and can enhance security by avoiding the inclusion of sensitive or unrelated information. This targeted export capability is commonly used to output data in formats such as CSV, Excel, or PDF, supporting the integration of grid data into reporting and analysis processes.

Several Vue.js grid components allow you to export selections, including:

  • DevExtreme HTML5 JavaScript Data Grid (part of DevExtreme Complete by DevExpress) provides the option to export a user-defined range to Excel or PDF in Vue.js applications.
  • Wijmo FlexGrid (part of Wijmo by MESCIUS) includes a "selection" export mode which gives users greater control over output by exporting a chosen range from the grid to PDF.
  • Handsontable by Handsoncode facilitates the export of selected ranges from a dataset in Vue.js apps, offering flexibility to share specific portions of complex or extensive grids.
  • Syncfusion JavaScript DataGrid (part of Syncfusion Essential Studio Enterprise) comes with options for exporting filtered, current page and selected records, and to Excel, CSV or PDF.
