Transform Angular Material Table Data into Colorful Icons

When building applications with Angular, you might find yourself needing to display data in a more visually appealing way. A common challenge developers face is transforming raw data into informative and engaging visuals. In this case, we’ll tackle how to replace standard letters in an Angular Material Table with different colored icons based on specific data values. If you receive abbreviations like A, Y, and N for answered, yes, and no respectively, follow along to convert them into user-friendly icons that enhance the user experience.

Understanding the Problem

Imagine you're using an Angular Material Table to display a set of responses that include simple letter codes:

A: answered

Y: yes

N: no

Displaying these codes as simple letters may not be the most effective way to convey information. Instead, you can improve usability by replacing these letters with colorful icons, such as:

A green tick for "Answered"

A yellow check for "Yes"

A red X for "No"

Step-by-Step Guide to Implementing the Icons

To achieve this transformation, we will utilize Angular's structural directive *ngIf within our table setup. This will allow us to conditionally display the appropriate icon based on the value of element.answer. Here's how you can do it:

Modify the Table Structure

Open the component where your Angular Material Table is defined and find the section where you declare the table rows. Your current code structure looks like this:

You will replace this line with the following implementation:

Implement Conditional Logic with *ngIf

Update the <td> element to check the value of element.answer and display the corresponding icon based on its value:

Use Icons or Images as Needed

You can either link to icon images or use mat-icons if they're part of Angular Material. For example, if you're using mat-icons, you could refactor as follows:

Conclusion

By using the *ngIf directive, it becomes easy to create dynamic, recognizable icons in your Angular Material Table that enhance user interaction. Rather than showing plain letters, you now have a table that communicates the status directly through visuals, making it far more user-friendly and visually appealing.

As you continue developing your Angular application, keep exploring ways to enhance the interface with similar techniques. Using icons effectively can vastly improve engagement and clarity for your users.



Implementing colorful icons instead of plain letters creates a smoother user experience and makes your web application look more professional. Try it out in your own Angular Material projects and watch how it transforms your data presentation!
