The Tables in the Project Auditor’s Assemblies, and Precompiled Assemblies tabs does not scale with the Project Auditor window size which leads to unused empty space and bigger scrollbars in the tables

Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Import the provided script "NewMonoBehaviourScript.cs"
3. Open the Project Auditor window (Window > Analaysis > Project Auditor)
4. Click the "Install Rules" button
5. Click the "Start Analysis" button
6. Open the "Assemblies" tab
7. Observe the table in the middle while resizing the Project Auditor window

Actual results: There is empty space on the right of the table

Expected results: The table scales with the window's width making use of the empty space

Reproducible with versions: 6000.3.5f1, 6000.4.0b5, 6000.5.0a5
