 2. Grid tables. This kind of tables can be used for complex tables where merge cells are needed. Grid tables use separator lines between data rows (header and body). 
 Separator lines are composed of "+" symbols and "-" or "=" between the "+" symbols. "="s are used to separate header and body. Columns MUST be aligned, meaning that 
 position of "+" must be the same for every separator line, unless merged columns are being used. Body rows are defined as pipe tables rows, by using "|" to separate cells. 
 However, separator lines can be defined for certain columns, which make possible to define merge cells.

 Diagrams can be specified by using UML diagrams. The recommendation is to generate the PlantUML diagram image by using any PlantUML online servers ([ETSI PlantUML server](http://tools.etsi.org/plant)), and adding both the source code (.puml) and the image files to the media folder. Then, the diagram can be added as a normal figure as described at [Figures](#-figures).
