title: How do I "name" columns/rows in pandas DataFrame for clarity?
body: <p>I'm trying to figure out how to "name" the rows and columns in my pandas DataFrame, for clarity. I'm not sure what it's called, but I'm trying to create a table like this:
  <a href="https://i.stack.imgur.com/Ym7jw.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Ym7jw.png" alt="enter image description here"></a></p>
  
  <p>Is there an easy way to add "Actual class" on top of the column names, and "Predicted class" to the left of the row names, just for clarification?</p>
