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:

```auto
{
   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

```auto
| id | name | desc |
| 0 | Sam | tall |

```

would have a structure of

```auto
{
   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.
