Multiple data sources for a (advanced)datagrid?

Question

Hi all,
I have two arrays of objects coming in from two different sources keyed on a single column called "id". They have the exact same column structure. I want to show these in a grouped column structure in advanced data grid. The question is can I do that without manually merging the two arrays?
Concrete example:
Array1: [{id:1, name:"Cooper", zip:"94536"},
             {id:2, name:"Corolla", zip:"94404"}]
Array2: [{id:1, name:"One", zip:"94555"},
             {id:2, name:"Camry", zip:"94403"}]
This will look like:
Id
Name
Zip
Source1
Source2
Source1
Source2
1
Cooper
One
94536
94555
2
Corolla
Camry
94404
94403
I would like to do this without creating an array like:
[{id:1, name1:"Cooper", name2:"One", zip1:"94536", zip2:"94555"},
{id:1, name1:"Corolla", name2:"Camry", zip1:"94404", zip2:"94403"}]
Charts are quite good at this since you can assign different data sources to different series and the axis defines the key on which the data will be merged. However, I could not find anything similar for tables.
Any pointers?
Thanks so much!

Answer 1

Come to think of it, is this even possible? How does a datagrid use its dataField parameter to lookup data? I am guessing data_array[row_index][col.dataField] would determine the value of a single cell at row_index and col. If so, my naive approach would require me to override the bracket operator so that the appropriate value is returned..
e.g. when a simple array of objects is used, you have [{name:John, lastname:Smith}], datagridcolumns dataField is then set to "name". Now I will have two separate arrays:
arr1: [{name:John, lastname:Smith}]
arr2: [{name:Smith, lastname:John}]
mergedarray will have a reference to both of them. Then when getKey("name", 1) is called, it will return a special key which can be used to access the name property from array 1, something like "name1". If I cannot override the bracket operator, mergedarray[0][name1] will return nothing.
I remember reading somewhere that this kind of override is not possible. Any ideas?
