Limitation: For backward compatibility, all IfcTableRow objects referenced by an IfcTable shall have the same number of Row Cells. The actual number of Cells shall be taken from the number of cells of the first IfcTableRow for that table. The number of Cells is calculated by the derived attribute NumberOfCellsInRow in the associated IfcTable.
Figure 22.214.171.124.A illustrates table row use.
Figure 126.96.36.199.B depicts how table rows were structured prior to IFC4 with the use of the IsHeading flag. Note that the use of the IfcTableColumn constructs should be used instead of the IsHeading flag (which remains for backward compatibility only).
