Hi @stevecgn12 ,
It happens because, your output is organized in an array of objects, it means, a list of rows containing individually a property for each column. If you want to access an specific row, you will need to isolate it from your array by filtering it (you can use the Filter Query from the 'List rows present in a table' action or the 'Filter array' action); if you want to include in your email a set of rows, you will first need to organize its data in another way (maybe in a text, or a HTML table).
If you know the row position (for example, let's assume that you want to access the 4th row of the table below), it is possible to access it directly with expressions, by using brackets and passing the index (in this case, the index will be 3, as the count starts in zero):


Expression: outputs('List_rows_present_in_a_table')?['body/value'][3]
Output:

Note: as mentioned before, each row is stored as an object, and each of the columns is an individual property, as you can see in the image above.
I recently wrote a blog post about how to read data from Excel, which explores the alternatives mentioned above: http://digitalmill.net/2023/07/19/reading-data-from-excel-tables-in-power-automate/
Also, feel free to provide more context about how do you want to organize its data in your email and we can help you to adjust your flow to reach that 🙂
