Value templates are defined in the schema for model fields. These are typically literal strings with property variable references. In some use cases, more complex logic for a value template requires a function to calculate the property value at runtime.
The Table constructor params.value function provides a centralized place to evaluate value templates. It will be invoked for fields that define their value template to be true.
The value template function is called with the signature:
The value template should return a string to be used for the given fieldName. The properties and params are corresponding arguments given to the API.
