Dynamic HTML: The Definitive Reference

Name

rules — NN n/a IE 4 DOM 1

Synopsis

Read/Write

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 set borders to be drawn only to separate borders, 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. Do not confuse this property with the rules[] collection of styleSheet objects.

Example

document.all.myTable.rules = "groups"

Value

Any one case-insensitive rules constant (as a string):

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

Default

None (when BORDER=0); all (when BORDER is any other value).
