There are component events `onSubviewExpand` and `onSubviewCollapse` on the Perspective table, but is there a way to prevent a certain Table row's subview from expanding?

I don't just want to prevent / allow all of the rows in a table, just certain row(s).

I have a table with orders and the subview contains more information on the order as well as a "Start order" button. I would like to prevent the subview from expanding if the order is already in a state other than "not started".

You can apply subview per row.

> Hi All, I’m working in Perspective, 8.0.16. Wondering if there is a way to apply the subview functionality in the Table component to a subset of rows. In the table below, for example, the Picking Area has a set of children areas to display, but the Merge Area doesn’t have any children. Is it possible to remove the icon and expand functionality just from the Merge row? Thanks.
