Dynamic HTML: The Definitive Reference

Name

RULES — NN n/a IE 3 HTML 4

Synopsis

RULES=”rulesConstant"

Optional

Defines where (if at all) interior borders between cells are rendered by the browser. In addition to setting the table to draw borders to turn the cells into a matrix, you can also set borders to be drawn only to separate rows, columns, or any sanctioned cell grouping (THEAD, TBODY, TFOOT, COLGROUP, or COL). The BORDER attribute must be present—either as a Boolean or set to a specific border size—for any cell borders to be drawn.

Example

<TABLE BORDER RULES="groups">...</TABLE>

Value

Any one case-insensitive rules constant:

all: Renders borders around each cell
cols: Renders borders between columns only
groups: Renders borders between cell groups as defined by THEAD, TFOOT, TBODY, COLGROUP, or COL elements
none: Hides all interior borders
rows: Renders borders between rows only
