This workflow demonstrates how to setup up and configure nodes in order to always join two tables based on all columns. Column Filter Widget nodes are configured to include all columns and this node by default provides array flow variables with included column names. These flow variables are then used in Joiner node to set all availabe columns as matching columns in order to compare differences between two tables for which we are sure they have same structure. Add columns in Table Creator nodes or change input data to see how it works.
