列固定機能を実装して、ユーザーが大きなグリッドを横方向にスクロールした場合でも可視性を確保

Locked column functionality (also known as frozen or pinned column) allows users to keep one or more columns static while scrolling horizontally through a grid. This is an essential feature for comparing data across a wide grid, ensuring that key information, such as a row identifier column, remains in view.

Several React grid components offer column freezing functionality including:

  • DevExtreme HTML5 JavaScript Data Grid (part of DevExtreme Complete by DevExpress) can pin key columns for easy reference while scrolling through wide datasets.
  • Wijmo FlexGrid (part of Wijmo by MESCIUS) freezes columns to maintain the visibility of essential data during horizontal scrolling.
  • Ignite UI React Grid (part of Infragistics Ignite UI) keeps critical columns in view while scrolling horizontally through extensive data.
  • KendoReact Data Grid (part of KendoReact by Telerik) locks columns for persistent visibility when scrolling extensively across data.
  • Syncfusion Grid control for JavaScript (part of Syncfusion Essential Studio Enterprise) freezes columns for continuous access to important data during horizontal scrolling.
