Struggling with data interpolation issues in Angular2+ while using Angular material table

I am having trouble adjusting the sample material data table to accommodate my own data...

This is how my data is structured:

export const DATA: any = {
  'products': [
    {
      'id': 1,
      'name': 'SOLID BB T-SHIRT',
      'price': '28.00',
      ...
    },
...
]

In contrast, the example provided by Material.angular.io has their data formatted like this:

export const DATA = [
  {
    "id": 1,
    "name": "Leanne Graham",
    "username": "Bret",
    ...
  },
  ...
]

Despite my best efforts, I can't seem to get my data structure to align properly for use in the HTML interpolation as demonstrated here:

<table mat-table [dataSource]="dataSource" class="mat-elevation-z8">
   <ng-container matColumnDef="id">
    <th mat-header-cell *matHeaderCellDef> id </th>
    <td mat-cell *matCellDef="let element"> {{element.id}} </td>
  </ng-container>

Is there something crucial that I am overlooking?

Answer №1

The current issue is that the data source is being directed towards an object instead of an array. To resolve this, a simple implementation could be used in the .component.ts file:

dataSource = DATA["products"]

Answer №2

The solution to your issue may lie in the way you are generating the dataSource. It seems likely that instead of passing an Array, you are passing an Object. I recommend specifying the dataSource using DATA.products for better results.

Answer №3

Give this a shot, it did the trick for me

import { MatTableDataSource } from '@angular/material';

Next step is to include the following in your ngOniInit()

ngOnInit() {
   this.dataSource = new MatTableDataSource(DATA);
}
