In this chapter, you learned how to configure the basics for our Grid panels so that we can get the best out of them when developing our applications. It is important to know what a Grid panel's capabilities are and how can we add custom functionality using column renderers, grid features, and grid plugins.

It's also important that you perform tests and play with different combinations (configurations and event listeners) so that you can recognize which ones you find more comfortable to use, depending on the different scenarios you may need for your applications. Most of the time, it's impossible to learn 100 percent all the Grid configurations or event listeners, but remember that you can always take a look at the Ext JS documentation.

In the next chapter, we will take a look at and learn about data views and templates in Ext JS. This chapter may help you enhance more things (visual appearance) in your grids (renderers and presentations using templates).
