Figure 10-2. The border, cellspacing, and cellpadding
attributes of a table
While all sorts of combinations of the border and cellspacing attributes
are possible, these are the most common:
• border=1 and cellspacing=0 produces the narrowest possible in-
terior and exterior borders: 2 pixels wide.
• border= n and cellspacing=0 makes the narrowest possible interior
borders (2 pixels wide) with an external border that is n + 1 pixels
• border=1 and cellspacing= n tables have equal-width exterior and
interior borders, all with chiseled edges just 1 pixel wide. All bor-
ders will be n + 2 pixels wide.
