The Append node will assemble two or more data sets of a similar structure into a single table. It aligns columns of the same name and data type and preserves the entries in columns that have no match in other appending data sets. Refer to the Construct User Manual within the Construct Application for a more complete explanation of the Append function. Go to Help > Contents > Index > Then use the search bar. Or watch the Append node video here at the website.
