グリッドデータをスクロールする際のコンテキストの維持

列ヘッダをグリッドの上部に固定することで、大規模なデータセットで作業する際のユーザーエクスペリエンスを向上

Fixed headers are a user interface element found in grids, particularly those managing large datasets. They comprise the top section of the grid, typically encompassing the row containing column labels and potentially additional rows with key information. Unlike the scrollable body of the grid, these headers remain anchored to the viewport, acting as a persistent reference point while users navigate through the data, thus improving user experience.

Several React grids support fixed headers including:

  • KendoReact Data Grid (part of KendoReact by Telerik) includes fixed headers that stay visible as you scroll, offering seamless navigation through massive datasets.
  • Wijmo FlexGrid (part of Wijmo by MESCIUS) allows you to lock headers in place for easy column reference, even with horizontal scrolling.
  • Syncfusion Grid control for JavaScript (part of Syncfusion Essential Studio) includes pinned headers that offer consistent context amidst complex data exploration.
  • Handsontable provides you with the ability to freeze rows or columns to keep key data points always in view.
