"First column" in word table page break border

[mj1856]

I'm using Word 2010 built in tables, and have selected the table theme called "Medium Shading 2 - Accent 1". It has darker shading for the first column, which is what I want.

When the table flows across a page break, it puts a thicker black border at the bottom to cap off the page, but it doesn't put it on the first column, which looks very wierd. Why doesn't it?

I can manually draw the border into place, but then it is attached to that specific row. If I ever add content above that position and the row pushes to the next page, the manually drawn border goes with it.

How can you control the borders that are drawn on a table specifically for a page break?
