[Task] New column needed for self-scattering level checking
We need another column in the table view of ADDIE interface for Mantid. Detailed description can be found in the following link, https://balsamiq.cloud/sd2jtfw/ptaj9k7 -- see the second wireframe there.
@halgh007 We probably want to wait until we finish implementing this issue and the one to be created for adding in the scroll bar.
