Ignition - Power Table Column

Hi

To configure the column of the Power Table, I can add the columns with a Header name and the DataType. However, once I have added it, I cannot rename the Header or change the Datatype of the column. I had to delete the column and re-create it again (with different column name or datatype). Is there any way I can just edit the column without deleting it ?

Please help. Thanks.
