The CellSpacing property corresponds to the Cellspacing attribute of the Table element. This attribute sets the space (in pixels) that the user's agent (browser) must leave between the left side of the table and the left edge of the first column on the left, the top border of the table and the top edge of the very top line, and the same for the right and the bottom borders of the table. This attribute also sets the space between cells.
