This can be easily changed using the Columns panel.
I have a data table with columns X1, X2, X3, and X4 and I want to rename these columns.

- Prepare a data table (this can be an MS Excel file, etc.) that contains the changed column names.
- Select the range of new column names and select Edit -> Copy (in the example below, it ranges from the first row, Temperature, to the fourth row, Weather).

- In the column panel of the data table for which you want to change the column names, select all the target columns and select Edit > Paste.
