The techniques that you implemented rely upon data at predictable locations on the page. When you receive an invoice, you do not know how many items the invoice might contain. There might be just one item, or there might be a hundred items, possibly spanning multiple pages. Taskmaster includes actions to handle line items grids. You define the region on the page that might contain line items and define the structure of one line item. Taskmaster can then scan the region and locate all of the individual line items.
Later, you can update the TravelDocs application to demonstrate various techniques that are related to line item grids, including recognition, validation, verification, and export.
