The KNIME Report Designer provides a report template for each workflow. Special nodes enable those data tables to be identified that should be available within the report.
With the KNIME Report Designer the creation of reports consists of two clearly separated tasks:
Select, transform, preprocess, filter and prepare the data you want to use in the report. This step is carried out in a KNIME workflow.
Design, style and edit the presentation of this data with the report template editor.
Thus, the KNIME workflow editor shows all the preprocessing that is performed on the data in a comprehensive way, while the report template editor reveals how the data will be presented in the report. This therefore prevents these topics from being mixed up.
