Hi Ben. Good to see you're still around and helping folks. It's very appreciated.
I just tried your suggestion and got the same result. I attached 2 images to clarify. First before hovering, then after hovering.
The tooltip appears, but it is within the <td> element and makes the table bigger. I want it to appear above the table and not change the DOM flow at all, but still be relative to it's parent. You know, like all tooltips do normally. Like when you hover over an <a> with a title="here's a tooltip" attribute.
Edit: changed the second image to make it more obvio
