default.table.rules

`default.table.rules`

The default column and row rules for tables using HTML markup

## Description

Tables using HTML markup elements can use an attribute named `rules` on the `table` or `informaltable` element to specify whether column and row border rules should be displayed. This parameter lets you specify a global default style for all HTML tables that don't otherwise have that attribute.

These are the supported values:

all

- Rules will appear between all rows and columns.

rows

- Rules will appear between rows only.

cols

- Rules will appear between columns only.

groups

- Rules will appear between row groups (thead, tfoot, tbody). No support for rules between column groups yet.

none

- No rules. This is the default value.

The border after the last row and the border after the last column are not affected by this setting. Those borders are controlled by the `frame` attribute on the table element.
