The Column Appender takes two or more tables and quickly combines them by
appending their columns according to the order of the tables at the input
ports. It simply appends columns from the second input table to the first
input table and does the same for any subsequent table if additional
(dynamic) ports were added. The node performs a simple and straight
forward join operation but can be faster if certain preconditions are met.
For more details please read the description of the "Identical RowIDs
and table lengths"-option below. When in doubt, use the Joiner.
If the input tables share some column names, the offending column
names from the bottom tables will be appended with "(#1), (#2) and so on".
Options
Input Ports
- If the option "Identical RowIDs and table lengths" is checked: a sorted table with n rows. Otherwise a table without restrictions.
- If the option "Identical RowIDs and table lengths" is checked: Another sorted table with n rows. Otherwise a table without restrictions.
- …
- Table contributing subsequent columns.
