Compare and map values between two array of objects in JOLT - json

Question

I need to map the headers and row values based on the dataKey value.
Input JSON
{
"headers": [
{
"dataKey": "col-0",
"displayName": "Product"
},
{
"dataKey": "col-1",
"displayName": "Dimension"
},
{
"dataKey": "col-2",
"displayName": "Output type "
}
],
"rows": [{
"col-0": "Medium ",
"col-1": "300x250",
"col-2": "HTML [Animate]"
}]
}
Expected Output
{
"Data" : {
"1" : {
"Product":"Medium",
"Dimension":"300x250",
"Output type":"HTML [Animate]"
}
}
}
Spec:
This is the JOLT Spec i am using currently it is not producing the expected ouptut
[
{
"operation": "shift",
"spec": {
"headers": {
"*": {
"displayName": {
"*": {
"#(2,dataKey)": {
"$": "Data.1.&",
"*": {
"#(6,rows.&)": "Data.1.&"
}
}
}
}
}
}
}
}
]
Please provide the jolt spec for above scanario. i tried but not able to get the expected result.

[
{
// segregate values of the same key and form respective arrays.
"operation": "shift",
"spec": {
"headers": {
"*": {
"displayName": "#(1,dataKey)"
}
},
"rows": {
"*": {
"*": "&"
}
}
}
},
{
// put every value array into temp array
"operation": "shift",
"spec": {
"*": "temp[]"
}
},
{
// map first index element as key and second index element as a value into the output
"operation": "shift",
"spec": {
"temp": {
"*": {
"1": "Data.1.#(1,[0])"
}
}
}
}
]
