border-spacing | NN 6 IE n/a CSS 2
| Inherited: Yes
Determines the size of the space (if any) between all cell borders in a table. This attribute requires that the border-collapse attribute be set to separate (which is typically the default value). If you include only one length value, it applies to both the horizontal and vertical cell spacing; for two values, the first applies to the horizontal and the second to the vertical. See Figure 11-2 for a synopsis of a table's numerous dimension definitions.
