Tabletop exercises are discussion-based sessions where team members meet in an informal, classroom setting to discuss their roles during an emergency and their responses to a particular emergency situation. A facilitator guides participants through a discussion of one or more scenarios. A simple table here means means that there is a maximum of one header row and one header column where a header column specifies the type of information in the column. In addition, there are no merged cells within a simple table. Below are examples of simple and complex tables.
