Griddle supports nested data. Assuming we have a dataset that looks like:

[
  {
    "id": 0,
    "name": "Mayer Leonard",
    "location": {
      "country": "United Kingdom",
      "city": "Kapowsin",
      "state": "Hawaii",
    },
    "company": "Ovolo",
    "favoriteNumber": 7
  },
  ...
]

We can use state from location if we define Griddle like this:

  <Griddle data={localData} plugins={[plugins.LocalPlugin]}>
    <RowDefinition>
      <ColumnDefinition id="name" />
      <ColumnDefinition id="location.state" title="State" />
    </RowDefinition>
  </Griddle>
