This .NET class wraps the AcDbDataTable ObjectARX class. 

The DataTable class provides a general-purpose repository for simple numeric, character, 3D point, or object ID information arranged in a two-dimensional table. It relies on two component classes: DataCell and DataColumn. A row of data is represented by an DataCellArray.
