Scanner Comparison By Vulnerability Types
1.       Fix layout landscape view (with 4+ tools it looks odd)
2.       Hide column if all values are ZEROs. I added test scans, removed the test scans 8 different scanners, then deleted them [see deleting scan bug above] and this report now shows all ZEROs.
3.       Why does Manual have its own column <-- It's not a scanner

Although, still keep displaying Manual
