html table id's are dynamic in nature for me to filter data based on dropdown value

I'm new to html & js. I'm leveraging render() function in python to convert a dataframe to html where I'm trying to add dropdown to the page. once the html page is generated, i'm finding table id to be randomly generated unique value for me to use it in javascript logic for dropdown to filter html data. Kindly could someone help me how to handle this scenario.
