Accessing expanded row data with subview

When creating a subview in a Perspective table, how do you pass data about the expanded row as a parameter to the subview? I can only see the data about the selected row, but not about the expanded one, unless I’m missing something.

The Table will pass the following paraneter structure to the subview:

{
   column: string | number;
   columnIndex: number;
   row: number; // This is the true row index, as it derived from the data source
   value: any;
}

where value is a dictionary whose keys are the column names of the Table.
A Table with values

|    id    |  name  |  desc  |
|    0     |   Sam  |  tall  |

would have a structure of

{
   column: string | number;
   columnIndex: number;
   row: number; // This is the true row index, as it derived from the data source
   value: {
      'id': 0,
      'name': 'Sam',
      'desc': 'Tall'
   };
}

So your “SubView” should have params structured in the same manner - unless you have no need for any of the values, at which point you can omit the key.
