// - Confirm it exists and is a function
// - Confirm it returns an API instance
// - Even if only a single column is selected
// - Create a table which uses the following for various columns (you might need to create multiple tables)
// - Integer (array based tables)
// - Function
// - String (object based tables)
// - Select multiple columns and confirm that the data source for each selected column is:
// - e.g. if `columns.data` is not set it should return an integer (array based tables)
// - if `columns.data` is a string it should return that string
// - if `columns.data` is a function it should return that function, etc
