Perspective Table Data and Columns Config from Datasets

When using the JSON return format in a Named Query, the column order and original column datatypes are lost. You can move a Named Query binding to a custom property of the component or view, then use this simple iteration expression to deliver the jsonified content to the table: 
 Binding on props.data 
 forEach(
	{path.to.source.dataset.prop},
	asMap(it())
) 
 Features Employed 
 
 Iterables  General behavior of all iterators. 
 forEach()  Loops through the dataset, calling the nested expression with one row at a time. 
 it()  Delivers the one row in dataset format (same column names and types as the source). 
 asMap() Converts the first row of the dataset it is given into a mapping (dictionary) of key-value pairs.
