Are you looking for a detailed example of how to implement an Angular Material table in your web application? Look no further! Angular Material is a popular UI framework for building web applications. It provides a set of reusable and accessible components that are easy to customize. In this article, we will explore a comprehensive example of using Angular Material table, including how to set it up, populate it with data, customize its appearance, and handle user interactions. By the end of this guide, you will have a solid understanding of how to effectively use Angular Material table in your Angular project.

Setting Up Angular Material Table

Before diving into the code, make sure you have Angular CLI installed. If not, you can install it using the following command:


    npm install -g @angular/cli
  

Once Angular CLI is installed, you can create a new Angular project by running the following command:


    ng new my-material-table-app
  

After creating the project, navigate to its root folder and install Angular Material and CDK using the following command:


    ng add @angular/material
  

This command will prompt you to choose a custom theme, set up global typography, and specify the desired components. For the purpose of this example, we will select a pre-built theme and the MatTableModule.

Now that Angular Material is set up in your project, you can proceed to create the Angular Material table component and populate it with data.

Populating the Angular Material Table with Data

In this section, we will create a simple example of an Angular Material table populated with static data. First, you need to define the data structure and create a data source for the table. You can use a TypeScript interface to define the shape of the data, as shown below:


    export interface UserData {
      id: string;
      name: string;
      progress: string;
      color: string;
    }
  

Next, create an array of mock user data and instantiate a MatTableDataSource with this array:


    const ELEMENT_DATA: UserData[] = [
      { id: '1', name: 'John', progress: '70%', color: 'primary' },
      { id: '2', name: 'Alice', progress: '40%', color: 'accent' },
      { id: '3', name: 'Bob', progress: '60%', color: 'warn' },
    ];

    dataSource = new MatTableDataSource(ELEMENT_DATA);
  

Now, in your Angular component, you can use the MatTableDataSource to bind the data to the table in the HTML template:


    <table mat-table [dataSource]="dataSource">
      
    </table>
  

With these steps, you have successfully populated the Angular Material table with static data. Next, let's explore how to customize the appearance of the table.

Customizing the Appearance of Angular Material Table

Angular Material provides a wide range of options for customizing the appearance of its components, including the table. You can modify the table's header, rows, and cells to match the visual style of your application. Let's take a look at some of the common customization options for an Angular Material table.

Customizing Table Columns

You can define the columns of the table using the matColumnDef directive and specify the header text and data binding for each column. For example:


    <ng-container matColumnDef="id">
      <th mat-header-cell *matHeaderCellDef> ID </th>
      <td mat-cell *matCellDef="let element"> {{element.id}} </td>
    </ng-container>
  

By using matColumnDef, mat-header-cell, and mat-cell directives, you can easily define the columns of the table and bind them to the data source.

Styling Table Rows and Cells

Angular Material table provides CSS classes for styling table rows and cells. You can leverage these classes to apply custom styles or highlight particular rows based on certain conditions. For instance, you can use matRow and matCell classes to add background colors or borders to specific rows and cells.

Additionally, you can use ngClass or ngStyle directives to dynamically apply styles based on the data being displayed in the table.

Adding Pagination and Sorting

Angular Material table offers built-in support for pagination and sorting. You can enable these features with minimal setup, allowing users to navigate through a large dataset and sort the table based on specific columns.

By customizing the appearance of the Angular Material table, you can ensure that it seamlessly integrates with the visual design of your application and provides a cohesive user experience.

Handling User Interactions

User interactions play a crucial role in the functionality of a table component. Angular Material table provides event bindings and directives to handle user interactions such as row selection, row click, and context menu actions. Let's explore how to implement some common user interactions with the Angular Material table.

Row Selection

You can enable row selection in the Angular Material table by using the matRow directive and matSelectionRow directive. This allows users to select one or multiple rows in the table, and you can capture the selected rows in your component logic.

Row Click Event

Angular Material table provides the (click) event binding to handle row click events. You can use this event to perform actions when a user clicks on a specific row, such as navigating to a detailed view or displaying additional information.

Context Menu Actions

Adding a context menu to the Angular Material table gives users the ability to perform context-specific actions on the table data. By utilizing the matMenuTriggerFor directive, you can associate a context menu with the table and execute custom actions based on the user's selections.

By effectively managing user interactions, you can create a seamless and intuitive experience for users interacting with the Angular Material table in your application.

Persistent Sorting and Pagination

Adding support for persistent sorting and pagination ensures that the table's state is maintained across user interactions and component updates. Angular Material provides a way to preserve the sorting and pagination state of the table even when the underlying data changes. You can achieve this by persisting the sort and pagination settings and reapplying them after data updates or component reinitialization.

FAQs

Q: Can I use Angular Material table with data from an API?

A: Yes, you can populate the Angular Material table with data from an API by fetching the data using Angular's HttpClient, and then assigning the retrieved data to the MatTableDataSource.

Q: Is it possible to customize the pagination behavior of the table?

A: Yes, Angular Material table allows you to customize the pagination behavior by providing options for items per page and handling page change events.

Q: Can I integrate Angular Material table with reactive forms for editing data?

A: Absolutely, you can integrate Angular Material table with reactive forms to enable inline editing of table data. This allows users to edit data directly within the table cells and submit the changes back to the server.

Conclusion

In conclusion, the Angular Material table is a powerful and versatile component that can enhance the presentation and interaction of tabular data in your Angular applications. By following this comprehensive example, you have learned how to set up the Angular Material table, populate it with data, customize its appearance, handle user interactions, and persist sorting and pagination settings. With this knowledge, you are well-equipped to leverage the capabilities of Angular Material table to create rich and dynamic data tables in your web applications.
