I am using Word 2002. I was experimenting with different table
border styles, and now I have applied a style that I can't undo.
After selecting the  table, I did the following:
1. Opened the Borders and Shading dialog.
2. Under Style, I select the last item in the list.
   It looks like 2 gray lines, one darker than the other.
3. Under Setting, I select All. The Preview diagram
   now shows the selected double line border style.
   The interior border shows a border around each
   individual cell.
4. Clicked OK to dismiss the Borders and Shading
   dialog.

Now, I cannot change the border style of interior cells
to have just a single line separating the cells. No
matter which line Style I choose on the Borders and
Shading dialog, the chosen line forms a boundary
around each cell individually rather than just a
single line between the cells.

What is special about the last double line Style in
the Borders and Shading dialog that causes the
border to be drawn around each cell individually
instead of between cells? How do I change back
to drawing a single border between cells? I have
already figured out workarounds. I am asking these
questions with the hope of learning something new
about Borders and Shading.

Thanks in advance,
