From all columns
Copy every column of the input through as an output, each under its own name
Ingredient Family: mappingIngredientsList
Outline Display: Copy every input column through unchanged
Details
One entry for a whole row: as the only entry of an outputMapping it reveals every output the endpoint declared, under the name the endpoint gave it, instead of one From formula per column. The columns keep their types exactly, lists and files included, so a later step reads them as the endpoint declared them.
It adds exactly the input’s columns and renames nothing, so another entry beside it that adds one of those names is the duplicate-column error; use From formula alone when a subset, a rename, or a computed value is wanted.
Local scope
The parent slot binds these (look up the slot in the parent to see how):
$inputsTable– The input table$mappingResult– A table that contains all mapped columns so far$matchTable– An optional table that contains columns that we may be trying to set values for
