Sheet To Go -- Word Wrap in Cells?

Around here people abuse Excel spreadsheets as repositories for text for Release tracking, Project tracking, Employee performance, Timekeeping reports, Compliance and Audit tables, etc blah blah. Most cells have lines of text that must wrap to fit the cell width. When viewing the xls files in Sheet To Go none of these cells are doing line wrap -- the cell contents trail off invisibly out of the cell. I couldn't find anything useful concerning cell formatting and line wrap in the Documents To Go User Manual for Android at Dataviz. Any ideas?
