Hey @Mentellus!
Row coloring currently isn't supported in the new table but it is a highly requested feature! For now, it's possible to add a status indicator to your column depending on its value. Row coloring is also supported in the legacy table.
In either case, it's possible to dynamically specify the ornamentation in the table itself. This is an example that uses the status indicator:

Or like this:
In any case, you can dynamically reference the underlying data. So if you're already making modifications to the data in your JS query before you display it you could just reference a flag you put on the row instead 
Is the table read-only?
