On January 10, 2006, Apple introduced iWork '06 at the Macworld Expo in San Francisco, which upgraded Pages to version 2 and Keynote to version 3. New features common to both applications included 3D charts, tables with formula support, reviewer comments, and shaped image masking. The addition of tables with formula support may have been added to quiet rumors of an Apple spreadsheet application. Since iWork's focus is on presentation, Apple gave a way to put most common spreadsheet features into a table while providing only limited additional functionality.
