AdaptTable for Angular CDK

Nested tables in Angular CDK

Open a row and the panel holds another Angular CDK table — the same component, not a hand-built list. Each person has recent orders; the inner table has its own columns and row keys.

nestedTable() mounts the kit's DataTable with defaults that keep the two tables from fighting over the URL. Rows with no nested table can still use rowDetail().

The expand chevron and both tables are Angular CDK.

The code

import { Component, input } from "@angular/core";
import type { ColumnDef, NestedTableDefaults } from "@adapttable/angular";
import { AdaptDataTable } from "@adapttable/angular-cdk";
import { nestedTable } from "@adapttable/angular-cdk/nested-table";

interface Order {
  id: string;
  item: string;
}

interface Customer {
  id: string;
  name: string;
  orders: Order[];
}

@Component({
  selector: "app-orders",
  imports: [AdaptDataTable],
  template: `
    <adapt-data-table
      [data]="row().orders"
      [columns]="columns"
      [rowKey]="rowKey"
      [urlSync]="defaults().urlSync"
      [searchable]="defaults().searchable"
      [tableLabel]="defaults().tableLabel"
    />
  `,
})
export class Orders {
  readonly row = input.required<Customer>();
  readonly defaults = input.required<NestedTableDefaults>();
  readonly columns: ColumnDef<Order>[] = [{ key: "item" }];
  readonly rowKey = (order: Order) => order.id;
}

@Component({
  selector: "app-customers",
  imports: [AdaptDataTable],
  template: `
    <adapt-data-table
      [data]="rows()"
      [columns]="columns"
      [rowKey]="rowKey"
      [features]="features"
    />
  `,
})
export class Customers {
  readonly rows = input.required<readonly Customer[]>();
  readonly columns: ColumnDef<Customer>[] = [{ key: "name" }];
  readonly rowKey = (row: Customer) => row.id;
  readonly features = [
    nestedTable<Customer>((row) => ({
      label: `Orders for ${row.name}`,
      table: Orders,
    })),
  ];
}
