From the web designer, it is possible to associate a table-type field to a task, then to describe this table by adding "sub-fields" corresponding to the columns.
On generation, for each table field defined in the process, a new resource template is generated and put as reference on the field itself. A resource form is also generated for typing fields of a table line.
On execution, the user can add a new line using the "Create" button. When this button is activated, a new internal resource is created.
