Detailed output tab row colors are too strong

The table formatting on the output tab uses alternating row colors. When users need to highlight cells with data issues for follow up, the highlighter colors are sometimes not visible or hard to see due to the strong colors in the row background. 

Need to remove row coloring, or switch it to something more subtle (e.g. light shades of gray).
