Rename columns in Table¶
Rename the Table columns.
Documentation¶
Rename columns in Table(s).
Select Text Mode to match column names with the search pattern as plain text. Select Regex Mode to use a regular expression (regex) for pattern matching. For more information about how to write regex, see Regular expression syntax.
Group references may be used in the replacement expression.
If several columns match the search expression resulting in the same column name, the last of the matching columns will be copied to the output and the other columns will be removed. Note that renamed columns (i.e. any columns that match the search expression) always take precedence over non-renamed ones.
