Creating a Customizable React Table for Weekly Activities

As you dive into the world of React, one challenge that may arise is creating a table that dynamically displays information based on JSON data. In this post, we'll walk through creating a customizable React table that represents activities scheduled for every hour from 1 PM to 5 PM over the days of the week. We'll filter and display entries from a JSON object all while avoiding repetition.

The Challenge

The goal is to create a table with:

5 columns, each for a different time slot (1 PM to 5 PM).

7 rows, each representing a day of the week (Sunday to Saturday).

You'll be working with a JSON object like this:

The challenge arises because multiple activities can fall on the same day and time. For instance, both Basketball and Golf may overlap in the 2 PM slot on Sunday.

The Solution

Step 1: Transform the Data

We’ll start by transforming the given JSON data into a structure that's easier to work with for our table. The transformation ensures that activities for the same day and time are grouped together in arrays.

Here’s how you can achieve that:

Step 2: Create the Table Component

Using the react-table library, we’ll create our table component, defining how our columns and cell rendering works:

Conclusion

Now you have a fully functioning customizable React table that maps activities to the correct time slots without redundancy. By leveraging react-table, you can dynamically display your data and make your application interactive and responsive to changes.

By following this structure and approach, you can easily adapt your table to handle more complex scenarios, such as adding more time slots or categories in the future. Happy coding!
