The TinyMCE Advanced Plugin will allow you to add additional toolbars to your TinyMCE editor in WordPress. The editor you see when creating or editing Posts and Pages in WordPress is called the TinyMCE. While the TinyMCE Advanced plugin can be used to add 16 plugins to your TinyMCE editor, for the purposes of this article, we will be focusing on adding tables.

Once you have installed and activated the TinyMCE Advanced Plugin, there are a few steps to take in order to add the Table button to your TinyMCE editor.
Go to TinyMCE Advanced under the Settings area of your WordPress dashboard.
To add the table tools to your editor, click and drag the table tools to one of the additional toolbar areas and click the Save Changes button at the bottom of the page.
Next, you can either edit an existing Page or Post or create a new Page or Post. You will now see additional buttons for adding and editing tables in a Post or Page.
