Three Column Postbit?

[10 Gauge]

Can someone please help me with the proper code for a three column postbit?

I have some very rudimentary HTML code for a table setup now but it honestly does not look the way I want it to and on the new style we are working on it pushes the middle column below the rest (I think due to spacing issues).

I would like help designing a proper 3 column postbit where each column is of equal length with the left column being aligned to the left, the middle column having a right align, and the right column aligned to the right.

Below is an example of how it looks now, as you can see the middle column is a bit of a drifter....

First pic is how it looks in the new style, the second pic is how it looks in the classic style.

Thanks in advance for any help!
