The Table Layout option gives users the ability to see an overview of all of their Roadmap items in one place.
Navigate to your Roadmap's Table Layout by clicking table icon in your Roadmap Header.
Once in the Table layout section of your Roadmap, you can choose whether you want to filter by Planned or Parked bars.
Planned bars are any of the in-flight items currently on your primary Timeline or List View. Any time an item gets added to your primary view, they will appear under the Planned area of your Table Layout.
The Parked section represents your Roadmap's backlog. It's a great place to store future items for prioritization or paused initiatives. For more information on managing your Roadmap's backlog click here.
From the Settings of the Table Layout, you can customize which columns you want to appear in your view. Click on the gear icon in the top right corner to see your options. By default, you can choose from the options in the below. If your account is utilizing Custom Fields, you will have the option to display that field as a column as well.
