cellspacing Attribute

Where to use the cellspacing Attribute

• As Type Length:
  cellspacing is declared on the element: table

Description

The cellspacing attribute specifies the spacing between each table cell (and also between the outermost cells and the edge of the table).

The cellspacing attribute is not present in the *W3C XHTML 1.1 Basic Tables Module.

An integer is treated as a pixel value and the spacing between cells will be this number of pixels. In theory, it is possible to specify instead a percentage value for this attribute, but a percentage of what is unclear - in fact my Firefox 2 browser seems to ignore percentage values entirely and my Opera 9 browser seems just to treat the percentage value as if it were a pixel value (i.e. "10%" is equivalent to "10"). It is therefore safer to stick to pixel values (or, better, CSS and the border-spacing and border-collapse properties).
