Spread Transformation

When a user sets a object column's fields as spread in the data source schema, the columns will show the first level properties of the object. This is useful for adding a nested object into the TableSheet without having to manually flatten the fields before data binding.

When a user fetches the following json ("Companies.json") from a server, and specifies that the "fields" column should be spread, then the above nested object will be converted to a plain object. id createdTime Opportunities Address Employees Name Description Type Contacts SumOpp Field 11 rec0kxKqvmMIFTmnF 2013-04-17T02:38:00.000Z recZgmDrnvRTxTvpI 8340 Clarington Avenue, Suite 2500, Culver City, CA 90232 4000 Liberty Pictures One of the minor studios of Hollywood's Golden Age, Liberty Pictures was ultimately acquired by Japanese multinational media conglomerate Cony in 1989.
