1. What are sub-tables?

Report sub-tables can be added using the familiar Tables logic. A sub-table could be, for example, a list of furniture in a room, or a list of doors assigned to a space.

Sub-tables can be configured like regular Tables lists (parameters, grouping/sorting, filters, display). Any number of sub-tables can be added to a report, as long as they are inserted below one another - not side by side.

2. Adding a sub-table

Use one of these commands in the report template: New Component List, Special Lists, Import Component List, or Table Presets.

Adding a furniture sub-table: the standard category selection dialog appears. The sub-table is inserted below existing template content.

3. Configuring the Smart Report linkage

Create the linkage in the Smart Report tab of the Component List Properties dialog. Here you connect a key parameter of the sub-table to the corresponding report element parameter:

In the Smart Report tab, the key parameter of the sub-table (left: Room:Id) is linked to the report element parameter (right: Id). The connection is made via identical parameter values.

4. Editing sub-tables retroactively

To edit a sub-table retroactively, activate a cell within the table. The ribbon automatically switches to the table commands (context-sensitive):

Via right-click or the Edit command you can access the table properties dialog again.

5. Special lists as sub-tables

All Special Lists can be used as sub-tables - provided a logical relationship to the report category exists:

Via New Component List - Special Lists, options like room boundaries, materials, model elements, view filters, and more can be added as sub-tables.

6. Grouped parameters

To display an aggregated value in a single cell - e.g. total furniture count in a room - use the Grouped Parameter command. Grouped parameters aggregate rule-based information from your Revit model into a single value.

When inserting a grouped parameter, the standard category selection dialog appears first - here furniture for a furniture count per room.

In the edit dialog, select the parameter to aggregate and the aggregation method:

Available aggregation methods: Default, Average, Count, Maximum, Minimum, Sum, and Minimum and Maximum.

In the Smart Report tab, define the link to the parent report element - exactly as with sub-tables:

Linkage in the Smart Report tab: key attribute Room:Id linked to key attribute Id of the report.

Use Edit to modify grouped parameters after the fact (select the cell first). Result in the template:

Result in the template: the Furniture count in room cell shows the aggregated value 208.
