Rename columns in Tables with Table¶
Documentation¶
Rename columns from the input data using a lookup table.
The lookup table must include one column with search keywords and another column with replacements. When the node is executed all column names in the input data are checked against keyword column in the lookup table. If a match is found the corresponding name in the replacement column will replace the original column name. For the case with no match the column names are left unchanged.
If a name appears more than once in the search column of the lookup, that column will be renamed to each of the replacement names. Essentially copying the single input column to several columns in the output.
If a name appears more than once in the replacements column the last one that is also present in the input data will be used. Also note that renamed columns always take precedence over non-renamed ones.
