Highlight a row - Data Table

I have a question that seems simple, but having some trouble implementing. I want to highlight the 2nd row in my data table. Based off the docs, I am using:

            'if': {
                'row_index': 1,  
            'backgroundColor': 'hotpink',
            'color': 'white'

However, when I run this, it highlights every alternate row instead of just the row at index 1. Any idea on how to approach this?

huh that’s odd - could you create a complete reproducible example with some dummy data?
