How to Display Object Properties in Nested Mat Table in Angular Using Angular Material

Creating a responsive user interface that displays complex data structures can be a daunting task, especially when dealing with nested data. In this guide, we'll explore how to create a nested mat table in Angular using Angular Material. Our primary focus will be on how to display specific object properties in the nested table instead of raw object data.

Understanding the Problem

When you are working with structured data in Angular, you often encounter nested objects. For example, let's consider a User interface that contains an array of Cars. Each Car has details like company, model, and parts, which are themselves objects. When we fetch this data and attempt to display it in a nested mat table, we often see raw objects instead of their properties, leading to a less user-friendly interface.

Example Structure

For clarity, let’s review our initial data structures:

The Solution: Mapping Object Properties

To effectively display specific properties of our nested objects (such as name for the company, model, and parts instead of raw objects), we can utilize Angular’s ability to access object fields easily in our template.

Step-by-step Implementation

Edit the HTML Template: We will update the template for our nested table.

Initially, we were displaying the entire object:

We need to replace this with a more specific property access:

Updated HTML Example

Here’s an adjusted version of the HTML component reflecting the changes:

Conclusion

By implementing these changes, you can easily map object properties to display more meaningful information in your nested mat table. This not only improves the aesthetics of your user interface but also enhances user experience by providing clearer data representation.

If you have more complex nested structures or need additional help, don’t hesitate to explore resources or ask for assistance in community forums. Happy coding!
