Defined in File Ifc4x2.h
IfcTable: public IfcUtil::IfcBaseEntity¶
An IfcTable is a data structure for the provision of information in the form of rows and columns. Each instance may have IfcTableColumn instances that define the name, description and units for each column. The rows of information are stored as a list of IfcTableRow objects.
Limitation: For backwards compatibility, the rows of an IfcTable object are constrained to have the same number of cells. The first Row of the table provides the number of cells. All other rows are forced to include the same number of cells. This is enforced by the WR2.
