# Local Table Data Source

## Overview

When a data source powers your app, you can continuously update your app contents without having to republish it. It allows you to build a dynamic app that can create, read, update, and delete data. This doc covers creating a local table as the data source.

## Create a Local Data Source

To create your own table as a data source:

1. Click the **data icon** in the left side panel to access your data source library.
2. Click the **plus sign** at the top of the panel.&#x20;
3. You can select from previously added data sources or add a new data source. Click **Create New**.
4. Select **Create your own table**.
5. Give your local data source table a name.
6. Click **Create**.
7. To add data to your local table, copy and paste it from another source or click into a cell and type to input the data.&#x20;
8. To modify the table's columns:
   * To **update** the table’s column headers, click their names and type a new header name.
   * To **add** additional columns, click the **+ New Column** button.
   * To **delete** columns, click the **x** in the column’s title box.
9. To modify the table's rows:
   * To **add** additional rows, with your cursor in the bottom row, press your keyboard’s enter or return key.&#x20;
   * To **delete** a row, right-click on it and select **Remove row**.
10. Select your preferred storage option:
    * **App Data Source** - If the data is changed while the app is open, the table's data resets when a user of your app closes and reopens the app. This reduces the time it takes for the app to load on the user's device.&#x20;
    * **Stored Data Source** - If the data is changed while the app is open, the table's data persists when a user closes and reopens the app. <br>

11. When your table is complete, click the **X** in the upper right.
12. The newly created local data source is now listed in your project's list of data sources.
    * Click the pencil icon to **rename** the data source.&#x20;
    * Click the data source's name to review and **edit** the data.
    * Click the trash can icon to **delete** the data source from your project.<br>

## Display the Data in Your App

Once you've connected a data source, you can display the data in your app with a data viewer component. Learn more about data viewer components here:
