Trouble displaying nested objects in DataTable

In the React Frontend, I need to display a nested property but it’s not showing. I’ve tried the following approaches in the columnDefinitions:

The data is shaped:
{
“status”: “ACTIVE”,
“demand”: {
“availability”: “EXTERNAL”
}
}
columnDefinitions={[
“status”,
{
columnProps: {
title: “Availability”,
key: “demand.availability”,
dataIndex: “demand.availability”
}
},
“demand.availability”,
"demand[‘availability’]

Is there another option to try?
