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:
- Type: TableFirst table to concatenateTable contributing the rows of the first part of the output table.
- Type: TableOptional second table to concatenateTable contributing subsequent rows (optional).
- Type: TableOptional third table to concatenateTable contributing subsequent rows (optional).
- Type: TableOptional fourth table to concatenateTable contributing subsequent rows (optional).
