Table widget enhancement

I have a need to design a table with 2x columns using the "percentage bars" with data points from differing Data Sources.

Currently the table widget only allows "percentage bars" to work on "Dynamic" tables and "Dynamic" tables only allow you to pull data points from a single Data Source.

Can the "Percentage bars" feature be added to "Custom" tables... or.. can "Dynamic" tables be enhanced to allow data points from multiple Data Sources?
