Once a report snippet has been set up through the "Report Columns" section of the snippet configuration page, the report columns are editable in two ways: 

• Hide a column. By un-checking the box in the "Show" column
• Rename a column. By editing the text in the "Display Name" column. If left blank, the column in the report will have a blank header. 

The reset arrows will return the above changes to the original format.
