- The border attribute sets the thickness of the frame around the
- table. The default units are screen pixels.
-
- The frame attribute specifies which parts of the frame around
- the table should be rendered. The values are not the same as
- CALS to avoid a name clash with the valign attribute.

- The rules attribute defines which rules to draw between cells:
-
- If rules is absent then assume:
