I have a tab container and have a table component inside. The table is taking up the whole container. Is there a way to add more components to this tab besides the table, and move them around like a coordinate container?
The tab container behaves more like a flex.
You can create a coordinate view and embed that in a tab using the Embedded View component.
Alternatively drop a View Canvas component onto the tab and embed as many view instances as required.
Each tab content is basically just like an embedded view: It takes one component only. But there's no rule that says this one component cannot be itself a container with more things inside.
So... Wrap your table into a container.
It doesn't have to be any particular type of container, it should work with coord, flex, another tab container...
