Rename columns in Table¶
Rename the Table columns by using regular expressions.
Documentation
Rename columns in Table(s) using a regular expression.
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.
