Filter List with Table¶
Filter nodes with Table input takes a table on the upper port and use it to filter the list on the lower port. The table must contain a single column which should be at least as long as the list on the lower port. Lets call it the filter-column. Now for each item in the incoming list the corresponding index of the filter-column is inspected. If it is True (or is considered True in Python, e.g. any non-zero integer or a non-empty string) the item is included in the filtered list. And vice versa, if the value in the filter-column is False (or is considered False in Python, e.g. 0 or an empty string) the corresponding item is not included in the filtered list.
