Highlight the table, choose "table properties," choose the tab that says
"table," then click on the "options" button at the bottom of the dialog box.
Your left and right borders are usually set for 0.08 inches. Change these to
"0" inches and see if that helps.

Problem is that whatever adobe distiller does when processing images
and tables this very small difference becomes quite noticeable.

My current plan is actually to set the image smaller than the cell size
and use a fill colour for the cell as the images should be using a
limted colour scheme.

Word doesn' t seem to very effective a 'cutting off' images larger than
the cell size
