NodeXL's worksheets have many columns, some of which you may never use. If you want to reduce worksheet clutter so you can concentrate on the columns that are important to you, you can tell NodeXL to hide some of the columns.
The columns are arranged in column groups. For example, the Edges worksheet includes Visual Properties, Label and Other column groups, and the Vertices worksheet includes the same column groups and several others. (The Other column group is where you can add your own columns to the worksheet.) NodeXL hides and shows workbook columns by column group.
