With your current flow, you are attempting to convert the time zone of an Excel value and it has nothing to do with the HTML table.
You need to convert the timezone before or when it is getting put into the HTML table.
You will need to make the HTML custom columns and then convert the timezone with an expression.
Here is a quick example, you should be able to use the expression with your time zone.
ConvertFromUtc SharePoint Created Time
Here is the expression to use. I put in your timezone after checking your photo.
convertFromUtc(item()?['Created'],'Eastern Standard Time','MM/dd/yyyy hh:mm tt')
Let me know if this works for you
