Custom Script Report CSS

How to use style.setStyle in custom script report ?
I aim to color row background based on condition in a script report.

First, you may run the report on your web browser.
You go Developer Tools and inspect the Elements to see the css / scss formats.
You try to change those css to the format you like.
You change the style in your script accordingly

frappe.query_report.datatable.style.setStyle(.dt-cell, {height: ‘200px’})
