border-spacing

The border-spacing property determines the spacing between cells. This has no effect unless border-collapse is set to separate.

Below an example of two tables with different values to the border-spacing property:

enter image description here (opens new window)

The table on the left has border-spacing: 2px (default) while the one on the right has border-spacing: 8px.

Value Description
This is the default behavior, though the exact value can vary between browsers.
This syntax allows specifying separate horizontal and vertical values respectively.
