For this challenge we will extract the table from this PDF document and attempt to partially reconstruct it within KNIME.The corresponding KNIME table should contain the following columns: Day, Max, Min, Norm, Depart, Heat, and Cool. Note 1: Yourfinal output should be a table, not a single row with all the relevant data. Note 2: The Tika Parser node is better suited for thistask than the PDF Parser node. We completed this task without components, regular expressions, or code-snippet nodes. Infact, our solution has a total of 10 nodes, but labeling the columns required a bit of manual effort.Author: Victor Palacios Dynamic download PDF Load PDF and parse content Dynamically identiftytable dimensions Parse the partial header names Split data table to columns Inside of component.
