A 
Table represents rows of data and can be added to 
Forms.
Tables are made up of columns and rows. Each 
Table Column has a name, a type and contains a single value for every row in the tabular data. The data can be fetched and saved from and to an external system, such as a database or an XML document, using Resources.
The Tables View 
in the top-right corner of the Form Editor lists all the Tables, and their Table Columns, added to the Form. Clicking on a Table or Table Column shows its properties in the Properties View.
To create a new Table click 
in the Tables View to open the New Table dialog, where an initial set of Table Columns can also be configured. The New Table dialog also allows you to select a Table (Multiple Row) Database Resource and import it's Resource Fields as Tables Columns.
You can add columns to an existing Table by clicking the 
button in the Tables View.
Tables can be dragged from the Tables View and onto the Page's 
Outline or WYSIWYG View to create a Table Control that an end-user can interact with.
