Column Filter

StreamableKNIME Base Nodes version 4.0.1.v201908131444 by KNIME AG, Zurich, Switzerland

This node allows columns to be filtered from the input table while only the remaining columns are passed to the output table. Within the dialog, columns can be moved between the Include and Exclude list.

Options

Include
This list contains the names of those columns in the input table to be included in the output table.
Exclude

Filter
Use one of these fields to filter either the Include or Exclude list for certain column names or name substrings.
Buttons
Use these buttons to move columns between the Include and Exclude list. Single-arrow buttons will move all selected columns. Double-arrow buttons will move all columns (filtering is taken into account).
Enforce Exclusion
Select this option to enforce the current exclusion list to stay the same even if the input table specification changes. If some of the excluded columns are not available anymore, a warning is displayed. (New columns will automatically be added to the inclusion list.)
