iirc, i made the base for that style. its a slight modification of "UBBT75 - Crimson" with borders enabled and a few other tweaks.
Borders is just the following code added to "Extra Properties" for the style
table{border-collapse:separate;border-spacing:1px;}
You can download the styles for past versions of UBB.threads in the Member Area downloads section
