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. :)
