Computers will ignore this attribute, so they will just see the bgcolor that is being used, unless they have a WebTV viewer installed (link below). Gradcolors can be used in a table, a table row or a table cell.

Gradcolors will "gradiate" from the bgcolor to the gradcolor. The gradangle determines the direction in which the color change takes place. Gradangles are entered in degrees.

Here's the code for an individual cell:
<td bgcolor="?" gradcolor="?"gradangle="?" height="75" width="75">

Here are some gradcolor samples in individual cells against different color backgrounds.
Samples on Black, right angles
Samples on White, right angles
