I\'ve been looking around for a solution to this and I can\'t make head nor tail from various places of how to get my table to do coloured rows without asking my own question.>
I simply want each row to be highlighted in either green, yellow or red depending on the value of a separate variable (not displayed in the table).
Renderers work on data in the table. That is components can only paint themselves when they have all the information needed to do the job.
So somehow you need to add the information to the table. This might be done be adding a 4th column that is hidden. Then the table still has access to the information required.
Then maybe you can use the suggestion in Table Row Renderering.
