Table Styles
Table Styles are pre-defined styles for tables that contain combinations of formatting elements such as fills, borders, and font colors. PowerPoint provides various such styles to choose from -- just a single click can make your selected table look great.

Callout Shapes
Generally Callout shapes are connected to another figure or visual -- and these shapes contain some text. Callouts are not just any shape -- most of the time, callouts also have an attached line, arrow, or another pointer style that identifies it with a certain figure or visual. So in simple terms, callouts are those extra shapes with text that add value to other visuals. On their own, you'll hardly find callouts used anywhere.

Select Table Cells, Rows, and Columns
While working with tables in PowerPoint, you will always need to select some particular part of the table to work upon. For example, you may have to select an individual table cell, or even separate rows and columns while performing various tasks such as populating tables with content, or adding and removing table rows/columns, or even merging and splitting table cells. Sometimes you will also need to select contiguous cells in both rows and columns, or even the entire table itself.

Attributing and Positioning Callouts
Callouts are shapes that allow you to do numerous tasks: you can add text indications, create pointers, and also create comic-book style speech and thought balloons. You can create something that will attract the attention of your audience by combining the callouts with illustrations or photos of characters (both human and animal). All of the 16 Callout shapes available in PowerPoint cannot be used for text and thought balloons -- mostly you can use 4 of these shapes. While Rectangular Callout, Rounded Rectangular Callout, and Oval Callout shapes are speech balloons, the Cloud Callout is essentially a thought balloon.

Caveats About Masters
While all the Masters that PowerPoint 2003 provides can make it easier for you to create consistent looking slides, there may be times when these Masters will not live up to your expectations. And it is important for you to be aware of these "caveats", so that you don't run into big problems without being aware!

Multiple Slide Masters
Every presentation you create has its own Slide Master, even if you are not aware. This Master governs the default attributes of all slides in your presentation such as the background, font choices, colors, and even the positioning of the placeholders -- this makes all your slides look consistent. However, even then some sets of slides within the same presentation may have disparate slide elements -- so you may have some slides that are governed by one Slide Master and other slides that are governed by a completely different Slide Master!
