Can we have a nested property field for a perspective table column?

Hi,
I have a simple object like:
data=[{
"name" : "Rush",
"address" :
{
"number" : "2112"
}
}]
In my perspective Table I have 2 columns
First column, field = name
Second column, field = address.number

Is this possible to do that ? I got no success making this works.

If it's possible, what is the correct syntax ?

No, the field expects a string key which matches either a top-level key in the objects, or a column in the dataset which is in data. To use the address number as a column, you'll need to modify the object in use so that the number key is at the top level.

Within a transform you could do something like this:

entries = []
for entry in value:
    entry["number"] = entry["address"]["number"]  
    entries.append(entry)
return entries
