Troubles with Report Component from 2 sources

I’m new to KNIME reporting and can’t figure out what I’m doing wrong in my attempt.

I have two sets of data that I want to show in two tables next to each other on a single page. In the first screenshot, you can see them both flowing in from the left to create Left Table and Right Table:

I selected all those ports and created a Component. Here is how it looks inside:

I am able to run the nodes here.

I have set the layout for my desired report and checked the box at the bottom:

But when I leave the component, I see an error message that something is not connected:

And I cannot run the component.

I’m probably fundamentally misunderstanding something basic. Perhaps I cannot have two different data sources in the same report?
