After you get the right data flowing into a panel, you can customize the panel’s appearance by using the Panel Preferences dialog box. Changing Panel preferences is a key part of getting your panels to look right. Some panels let you make relatively minor changes, but in some cases, preferences let you customize the entire look and feel of the panel.
To open the Panel Preferences dialog box, click the Panel Preferences icon in the upper right corner of the panel.
The options available here will change depending on the type of panel selected. For Table, the Panel Preferences dialog box lets you set the number of rows displayed, the table’s style, and whether or not the table scrolls, among other options.
