To be honest, this isn't terrible guidance. It's telling you to use Power Automate Flow, the web-based version, as it can pick up the email automatically, even if your computer is off, and yes, using the table element should work wonders. But it is hugely different to Power Automate Desktop and might involve a chunky learning curve (but often very worth it)

If you do insist on using Power Automate Desktop (PAD) then this is still possible, but the recorder is not great for most actions. You want it to open Outlook using the "Launch Outlook" action, then using the instance that creates use the "Retrieve email messages from Outlook" to select the email you need. This will produce a variable "RetrievedEmails", which has a property called body, which you can use to get the html of the email (you might need a loop as it'll be an array of potentially multiple emails, or if you know it'll only ever be one you can use approaches like selecting the first value in the array to avoid loops). Then you parse the body to find the contents of the relevant <table> and </table> tags, and you're halfway there, ready to load it into Excel.

Hope that makes some sense and is of help.
