To be able to edit code and run cells, you need to run the notebook yourself. Where would you like to run the notebook?

This notebook takes about 3 minutes to run.

In the cloud (experimental)

Binder is a free, open source service that runs scientific notebooks in the cloud! It will take a while, usually 2-7 minutes to get a session.

Define a nested struct that we'll create tabular UI for. This is standard Julia code, nothing specific to PlutoTables.

Now, let's see some examples of PlutoTables UIs and layouts to modify this object.

Target values are specified as Accessors optics, and each is associated with a PlutoUI input element using the Pair syntax: optic => input.

Note how the syntax is similar to optimization problem specifications in the AccessibleOptimization package.
