Mantenha colunas importantes visíveis nas grades do React

Novembro 27, 2023
Implemente a funcionalidade de congelamento de colunas para garantir a visibilidade mesmo quando os usuários rolam horizontalmente por grades grandes.

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.
