JointJS — how to make an html table with the ports?

In JS I am a newbie, alas. In the documentation there is an example how to insert html into a rectangle, and here's how to use the object Model (need to be able to use the ports and connections between them), inside which is an html table, and the ports will be bound to the table rows?

Or maybe there is some other (free, preferably), library, where you can build a visual connection between the table cells? Preferably with examples. Thank you.
