I have created one plugin using **Builder** plugin in **OctoberCMS** and in which I have **columns.yaml** file. 

In a field called `property_id`, I have a field as **VALUE FROM** which is asking to add my table's field name hence I have added one called as `street_number`.

But I want to concat multiple fields there. Something like below.

```
CONCAT(street_number, ' ', address)

```

But this is not working. I have also tried with other ways but its still not working.

Can someone guide me how to accomplish this ? 

Additionally, It will be great if these fields gets concat if their respective values exists in table.

This is how my **columns.yaml** file looks like.

```
columns:
    property_id:
        label: Property
        type: text
        searchable: true
        sortable: false
        relation: Property
        valueFrom: street_number
    start_datetime:
        label: 'Start Date Time'
        type: datetime
        searchable: true
        sortable: true
    end_datetime:
        label: 'End Date Time'
        type: datetime
        searchable: true
        sortable: true
    status:
        label: Status
        type: number
        searchable: true
        sortable: true
        select: 'CASE WHEN (status =  ''1'' ) THEN ''Active'' ELSE ''Inactive'' END'

```

Thanks
