If you are tabulating data that has blank cells they will be displayed as blank cells in a Phoenix WinNonlin table. If you wish to display blank cells differently you want to do a search/replace. First select ‘Table Body’ in the tree under options. Select to Match the entire cell and don’t type anything in the ‘Search For’ field but type your conversion in the ‘Replace With’ field. Click ‘Add’ and reexecute the table.
