Column Filter (by Index)

This component allows to filter columns by their index (i.e. position). An example can be: select the second and the last columns (e.g. with "2,-1").
Configuration takes a string of column positions.

The component requires the following extensions:
- KNIME Expressions (https://hub.knime.com/knime/extensions/org.knime.features.expressions/latest)

Options

Column positions

Individual columns are separated by a comma. Negative numbers count columns from the back. For example, "-1" corresponds to the last column. Numbering starts with 1. Zero is not a valid input.
