## Building a Table ## Building a Table
We have found that one of the most useful things you can do to understand how your app works One of the best ways to understand how your app works is to get access to its underlying data, which are used to display items on screen. An efficient way of achieving this is by showing the data in a table.

### Configuring the table ### Configuring the table

You now have a Row type that describes the data you'll be storing and a description of the columns to display. With these components it's a trivial task to get a table showing data, including search / sort and a details view, as shown in the following code snippet:

The `method` refers to the method that should be listened to to fill the table with data. The above code snippet has the following properties:
The string `"newRow"` that is used here refers back to identifier we used with `connection.send` to send our data to the Flipper desktop application in the previous step.
The `key` property is optional, but by setting it the `'id'` field will be used as identifier. As a result, once a `newRow` message arrives with an existing `id`, it will overwrite the old entry, rather than appending a new one. * `method` - refers to the method that should be listened to to fill the table with data.

Starting Flipper will now compile your plugin and connect to the native side. It's a good idea to start Flipper from the command line to see any potential errors. The console in the DevTools is a great source of information if something doesn't work as expected, too.
