The Absolute Minimum
Tables are really easy to create and use because Keynote makes them that way. When you work with tables, keep the following issues in mind:
Think carefully about table content. Use tables to present contrasting information and data that can be viewed in a visual way. Tables work great for series of numbers and information that functions on a timetable basis.
Enter table text and content just as you would with any other slide element. Use the Fonts dialog box to make adjustments to fonts and text colors as needed.
Use the Table Inspector to adjust the rows and columns of a table. You can also use the Table Inspector to manage text alignment, cell borders, and cell backgrounds, including background formatting for the entire table.
