Thanks Tony. Well, I think you're on to something with the left and right margins. I checked the margins of the cell that is having the problem, and no margin indicators appear in the ruler!

I tried creating the table in a fresh Word document and didn't have any problems. Then, I tried copying and pasting that new table into the original document. Unfortunately, the problem returned - I suspect there is something in the styles (provided with the Word template I downloaded from Microsoft office) that is causing the problem.

Unfortunately, I can't send you the document as it's a confidential business plan.

What I ended up dong is creating the table in a fresh Word document, taking a screenshot and then pasting the screenshot into the original document. Not a perfect solution, but ultimately I'm going to print the document to Acrobat, so it will appear fine.

Thanks again for your help!

Frank
