Concatenate (Optional in) (deprecated)

This node concatenates tables, inputs are optional. Columns with equal names are concatenated (if the column types differ the column type is the common base type of both input column types). If one input table contains column names that the other tables do not, the columns can either be filled with missing values or filtered out, i.e. they will not be in the output table. The dialog allows setting the following parameters:

Input ports

1. Type: Table
   First table to concatenate

2. Type: Table
   Optional second table to concatenate
   Table contributing subsequent rows (optional).
3. Type: Table
   Optional third table to concatenate
   Table contributing subsequent rows (optional).
4. Type: Table
   Optional fourth table to concatenate
   Table contributing subsequent rows (optional).

Output ports
