Yes, it is possible to add a watermark to one cell in a table in Word 2003. Here are the steps to do it:

1. First, select the cell where you want to add the watermark.
2. Go to the "Format" menu and select "Borders and Shading".
3. In the "Borders and Shading" dialog box, go to the "Shading" tab.
4. Click on the "Fill Effects" button.
5. In the "Fill Effects" dialog box, go to the "Picture" tab.
6. Click on the "Select Picture" button and choose the image you want to use as the watermark.
7. Click on the "OK" button to close the "Fill Effects" dialog box.
8. Click on the "OK" button to close the "Borders and Shading" dialog box.
9. You should now see the watermark in the selected cell.

Note that the watermark will only be visible in Print Layout view or when you print the document. It will not be visible in Normal view or Web Layout view. Also, the watermark will be behind the text in the cell, so you may need to adjust the cell's formatting to make the text more visible.
