Agrupación de filas React

La tabla de datos Ignite UI for React / cuadrícula de datos le permite agrupar filas en un grupo de filas de 'encabezado fijo'. Esto es similar a la función Agrupar por de Microsoft Outlook, que es una manera fácil de agrupar datos visualmente en función de sus propios criterios.

React Row Group-By Area Example

Group-By Area

Set isGroupByAreaVisible property on the DataGrid to True, as shown in the example above, to the user interface. The group-by area allows users more options to group and sort columns without interact when interacting the DataGrid indirectly. Groups can be positioned and reordered based on the users needs. This area also populates when columns are programmatically added as groupDescriptions on the DataGrid as well.

Using Group Descriptions Example

Hierarchical Groups

The groupHeaderDisplayMode property allows the groups to be hierarchical. By default, each group description that is added gets aggregated together. Setting the groupHeaderDisplayMode to Split will create a section header for ever group defined in groupDescriptions property of the IgrDataGrid.

import { GroupHeaderDisplayMode } from 'igniteui-react-core';

public componentDidMount() {
    // ...
    this.grid.groupHeaderDisplayMode = GroupHeaderDisplayMode.Split;
}

Collapsable Groups

Also, the IgrDataGrid can display a toggle on each group section to allow the end user to expand or collapse the grouped data via the isGroupCollapsable property.

public componentDidMount() {
    // ...
    this.grid.isGroupCollapsable = true;
}
