Dynamic Data Table Component With Angular Material

D

Dynamic table component for angular built on top of the angular material table. It offers sorting, pagination, filtering per column, and the ability to specify content types and components used for displaying them. The initial purpose of this library was to display data coming from OData API, although it can work with MatTableDataSource, however, it needs to be extended to enable filtering

What is an angular table component?

Angular Table Component is a built-in component in Angular that allows developers to display data in a tabular format. It provides a convenient and easy-to-use interface for creating dynamic, data-driven tables that can be sorted, filtered, and paginated.

The Angular Table Component is highly customizable and supports a variety of table configurations, including dynamic columns, cell templates, and row templates. It also supports two-way data binding, which allows developers to bind table data to form inputs, making it easy to edit and manipulate data directly in the table.

It is a powerful tool for displaying large datasets and is commonly used in web applications for displaying data in a user-friendly format.

Getting started

1. Prerequisites:

Angular material: Please follow https://material.angular.io/guide/getting-started
 The supported version of Angular Material will be indicated by the major version number of this library. Version 8.3.0 is for Angular Material ^8.0.0, version 9.3.0 is for ^9.0.0, while versions <1.3.0 should work for versions <8.0.0.

Filter is using material icon, so adding material icons may be needed as well: https://material.angular.io/guide/getting-started#step-6-optional-add-material-icons

2. Install material-dynamic-table:

npm install material-dynamic-table --save

3. Import the installed libraries:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

import { DynamicTableModule } from 'material-dynamic-table';

import { AppComponent } from './app';

@NgModule({
  ...
  imports: [
    ...

    DynamicTableModule
  ],
})
export class AppModule {}

4. Include mdt-dynamic-table in your component:

<mdt-dynamic-table [columns]="columns" [dataSource]="dataSource"></mdt-dynamic-table>

5. Specify column definitions and data source:

import { Component } from '@angular/core';

import { ColumnConfig } from 'material-dynamic-table';

@Component({
  selector: 'app',
  templateUrl: './app.component.html',
})
export class AppComponent {
 columns: ColumnConfig[] = [
    {
      name: 'product',
      displayName: 'Product',
      type: 'string'
    },
    {
      name: 'description',
      displayName: 'Description',
      type: 'string'
    },
    {
      name: 'recievedOn',
      displayName: 'Received On',
      type: 'date'
    },
    {
      name: 'created',
      displayName: 'Created Date',
      type: 'date',
      options: {
        dateFormat: 'shortDate'
      }
    }    
  ];

  data: object[] = [
    {
      product: 'Mouse',
      description: 'Fast and wireless',
      recievedOn: new Date('2018-01-02T11:05:53.212Z'),
      created: new Date('2015-04-22T18:12:21.111Z')
    },
    {
      product: 'Keyboard',
      description: 'Loud and Mechanical',
      recievedOn: new Date('2018-06-09T12:08:23.511Z'),
      created: new Date('2015-03-11T11:44:11.431Z')
    },
    {
      product: 'Laser',
      description: 'It\'s bright',
      recievedOn: new Date('2017-05-22T18:25:43.511Z'),
      created: new Date('2015-04-21T17:15:23.111Z')
    },
    {
      product: 'Baby food',
      description: 'It\'s good for you',
      recievedOn: new Date('2017-08-26T18:25:43.511Z'),
      created: new Date('2016-01-01T01:25:13.055Z')
    },
    {
      product: 'Coffee',
      description: 'Prepared from roasted coffee beans',
      recievedOn: new Date('2015-04-16T23:52:23.565Z'),
      created: new Date('2016-12-21T21:05:03.253Z')
    },
    {
      product: 'Cheese',
      description: 'A dairy product',
      recievedOn: new Date('2017-11-06T21:22:53.542Z'),
      created: new Date('2014-02-11T11:34:12.442Z')
    }
  ];

   dataSource = new FilteredDataSource<object>(this.data);
}

Properties

Methods

ColumnConfig definition

ColumnConfig is used to provide specification for the columns to be displayed

Cell types

By default there are two types provided:

string

This displays plain string value for property defined under name in ColumnConfig. This is the default type used if there is no type specified for the data type.

date

This type will format property from ColumnConfig.name as date. It can take additional parameter in ColumnConfig.options – dateFormat, which specifies what date format should be used (default is ‘short’)

Adding additional cell types

New cell types can be defined by adding a component, inheriting from CellComponent

Here is an example of options cell that can be used for showing possible actions

import { Component, Input } from '@angular/core';
import { CellComponent, ColumnConfig } from 'material-dynamic-table';
import { Product } from '../../product';

@Component({
    selector: 'ld-options-cell',
    template: `<mat-menu #appMenu="matMenu">
  <button mat-menu-item  (click)="showDetails()">View Details</button>
</mat-menu>

<button mat-icon-button color="primary" [matMenuTriggerFor]="appMenu">
   <mat-icon>more_vert</mat-icon>
 </button>`
})
export class OptionsCellComponent implements CellComponent {
    @Input()
    column: ColumnConfig;

    @Input()
    row: Product;

    constructor() {}

    showDetails() {
        const productName = this.row.product;

        alert(`Product name is ${productName}.`);
    }
}

Cell types then need to be registered:

import { OptionsCellComponent } from './cells/optionsCell/options-cell.component';

@NgModule({
  ...
  declarations: [
    ...

    OptionsCellComponent
  ],
  entryComponents: [
    ...
      
    OptionsCellComponent
  ]
})
export class AppModule {
  constructor(private readonly cellService: CellService) {
    cellService.registerCell('options', OptionsCellComponent);
  }
}

Adding filters

Filters icon an the column will be displayed whenever there is a registered filter for that columns type. To add a filter first create a component for modal dialog with a model that implements your filter interface. Then register it in the following way:

import { TextFilterComponent } from './filters/text-filter/text-filter.component';

@NgModule({
  ...
  declarations: [
    ...

    TextFilterComponent
  ],
  entryComponents: [
    ...
      
    TextFilterComponent
  ]
})
export class AppModule {
  constructor(private readonly columnFilterService: ColumnFilterService) {
    columnFilterService.registerFilter('string', TextFilterComponent);
  }
}

In this case it is a filter for string cell type named TextFilterComponent. See the example project for full design. To make use of filters you need to have data source that can handle them. See FilteredDataSource from the example to see how MatTableDataSource can be extended to handle it.

Filters can have a description that is displayed when the filter is applied. To set the description for the filter the filter model should have a method getDescription that returns a string. Implement interface ‘FilterDescription’ for your filter model to have the description displayed.
