1.11.4. Insert/Delete Columns
You can add columns to, or delete columns from, the compound spreadsheet. The simplest way to add a new column is to right click on an existing column header (the gray cell at the top) and choose one of the menu options under Insert Column. This operation inserts a new column of the specified type immediately to the left of the selected column. The simplest way to delete a column is to right click on its header and choose Undisplay Column. Removing more than one column at once is described in this section.
