This .NET class wraps the AcDbTableStyle ObjectARX class. 

TableStyle class objects are used to store the table formatting properties (for example, grid visibility, lineweight, line color, and cell font, height, color, and background fill) used by Table entities. 

Because tables appear in a variety of forms, table objects will be based on a table style similar to the way text objects and dimension objects are based on styles in AutoCAD. The table style controls the initial formatting of a newly created table object and whether the table includes a title and header row.
