既存のワークシート内の新しいデータポイント、計算、報告のニーズに対応するために、オンデマンドで簡単にカラムを追加可能

Inserting columns is a fundamental spreadsheet capability that allows users to add new columns at any position within a worksheet without disrupting existing data. This feature helps accommodate changing requirements, making it easier to expand datasets, introduce new calculations, capture additional information, and reorganize content while maintaining the overall structure of the spreadsheet.

Several React spreadsheet controls offer the ability to insert columns, including:

SpreadJS allows users to insert one or more columns before or after a selected column through its spreadsheet interface and API, automatically adjusting formulas, references, and worksheet structure as needed.
Jspreadsheet Pro provides interactive column insertion directly within the grid, enabling users to add columns dynamically while preserving existing data and supporting further customization through its JavaScript API.
KendoReact Spreadsheet includes column insertion capabilities that mirror familiar desktop spreadsheet experiences, allowing users to add new columns through the user interface while maintaining workbook consistency and updating related spreadsheet elements.
Infragistics Ignite UI for React Spreadsheet supports inserting columns within worksheets through both user interactions and programmatic control, ensuring that data layouts can be expanded while preserving formulas, formatting, and spreadsheet integrity.

地域言語や文化的慣習をローカリゼーションで支援し、スプレッドシートアプリケーションをよりアクセスしやすく直感的に

Localization in spreadsheet components enables applications to present spreadsheet interfaces, menus, dialogs, functions, and user-facing messages in the user's preferred language and regional format. This helps organizations deliver a more familiar and accessible experience to global audiences while supporting regional conventions such as date formats, number formatting, currencies, and translated interface elements. By adapting the spreadsheet environment to different languages and cultures, localization can improve usability, reduce training requirements, and help applications meet the expectations of international users.

Several ASP.NET Core spreadsheet controls offer support for localization including:

DevExpress ASP.NET Core Spreadsheet provides localization support for its user interface, allowing developers to translate dialogs, menus, and other interface elements while also supporting culture-specific formatting for dates, numbers, and currencies.
