Concatenate

This node concatenates two tables. The table at inport 0 is given as the first input table (top input port), the table at inport 1 is the second table, resp. 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 table does 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:
