RoaringApps is maintaining a wiki listing hundreds of Mac applications and what is currently known about their compatibility with Lion. Anyone can add entries to the list or modify existing information. Although the information is preliminary (and not all of it comes from official sources), it can serve as a useful guide for people preparing their disks for an upgrade to Lion next month.follow link
Data Tables in Microsoft Excel 2008
Data Tables let you see how the results of a formula change as its underlying variables change. After entering data, select the entire table and choose Data > Table. Then tell Excel which row input cell and column input cells you want the table to use. Finally, click OK. Excel will crunch the numbers and present a new Data Table.
