by providing the
bgcolor
attribute or a style attribute for those rows or
cells.
The
background
attribute, a nonstandard extension supported by all the
popular browsers, supplies the URL of an image that is tiled to fill the
background of the table. The image is clipped if the table is smaller than
the image. By using this attribute with a borderless table, you can put
text over an image contained within a document.
10.2.1.3. The border attribute
The optional
border
attribute for the
<table>
tag tells the browser to
draw lines around the table and the rows and cells within it. The default
is no borders at all. You may specify a value for
border
, but you don't
have to with HTML. Alone, the attribute simply enables borders and a set
of default characteristics. With XHTML, use
border="border"
to achieve
the same default results. Otherwise, in HTML or with XHTML, supply an
integer value for
border
equal to the pixel width of the 3D chiseled-edge
lines that surround the outside of the table and make it appear to be
embossed onto the page.
10.2.1.4. The frame and rules attributes
With Netscape 4, the
border
attribute was all or nothing, affecting the
appearance and spacing both of the frame around the table and of the
rule lines between data cells. Internet Explorer versions 4 and later and
Netscape 6 and later versions, as well as the popular Firefox and Opera,
let you individually modify the various line segments that make up the
borders around the table (
frame
) and around the data cells (
rules
).
The standard
frame
attribute modifies
border
's effects for the lines that
surround the table. The default valuewhat you get if you don't use
frame
at allis
box
, which tells the browser to draw all four lines around the
table. The value
border
does the same thing as
box
. The value
void
re-
moves all four of the
frame
segments. The
