Extract Column Header
Creates new table with a single row containing the column names.
The node has two outports: The first port contains
the column headers (all columns are of type string, there is only
one row in the table) and the second outport contains the input
data, whereby the column names are changed to a default pattern
(given that the corresponding option is set.)
Dialog Options
- Use new column names
- Select this to replace the
original column names by a pattern. The pattern is to be set in the
corresponding text field. If not selected, the original column names
will be used in the output table (the second
output will be a reference to the input table.)
- Prefix
- Prefix of the new column names
- Selected column type
- Select the type of the column to
process, e.g. only use double-compatible columns.
