Hi @Anonymous,
I have made a test on my side and have created a sharepoint list as below:

You could refer to screenshot below to create the flow:


The expression of Emp ID in the Create HTML table as below:
item()?['Emp_x0020_ID']
The expression of Requester Name in the Create HTML table as below:
item()?['Requester_x0020_Name']?['DisplayName']
The expression of Email Id in the Create HTML table as below:
item()?['Email_x0020_Id']
The flow would run successfully as below:

The email would be sent as below:

Best regards,
Alice
