There is no 'background' attribute for <table> or <td>, only for <body>.
The validator is correct in flagging this as an error.

Netscape and MS browsers support a variety of "extensions" to HTML that
are not part of any W3C DTD.  Valid HTML that declares a W3C DTD must
not, therefore, use them.  The 'background' attributes are one example.

If you want to maximise accessibility, you would be far better served to
use HTML 4.01 Strict and CSS.  See the Web Content Accessibility
Guidelines [1].

CSS will do the job nicely, while also allowing validity and
accessibility  "background: url(foo.jpg);".
