Values of the frame attribute
A
table rule
specifi es how the internal gridlines are drawn within a table. To apply a
table rule, you add the
rules
attribute to the
table
element using the syntax
<table border=”
value
” rules=”
type
”> ... </table>
where
type
is
all
(the default),
cols
,
groups
,
none
, or
rows
. Figure 5-27 displays the
impact of each of these
rules
attribute values on the placement of the internal table
gridlines.

Values of the rules attribute
By combining
frame
and
rules
values, you can duplicate many of the same effects
you could achieve using the CSS
border-style
property, which you'll explore shortly.
Some Web page authors prefer to work with these HTML attributes because they enable
them to set the appearance of the table borders from within the
<table>
tag rather than
through an external style sheet.
