Please help: Need space borders in postbit cells (css)

[NietzscheKid]

Hello

I am having a huge problem in getting a space between each cell within the postbit. I have tried the border-spacing but that did not work. I am no good in such things and hope one of the css gurus can help me out.

Here is my postbit

(as you can see, the cells are collapsed, there is no space between them which I don't know how to solve).

And here is a sample of how it should look:


Any help would be greatly appreciated.
