Which nerve from the spine innervates the colon?

In brief: You asked for it

Sympathetic fibers from the spinal cord lead to the celiac ganglion (foregut) and superior (midgut) and inferior (hindgut) mesenteric ganglia.
Parasympathetic fibers arise from the vagus (innervate the foregut and midgut (through transverse colon)) and the hindgut (pelvic nerves which innervate the descending colon, sigmoid, and rectum). Does that answer your question?

In brief: Autonomic

The colon is inervated by sympathetic and parasympathetic branches of the autonomic nervous system.
The sympathetic branch relatively shuts down intestinal function, which is superfluous during "fight or flight". The parasympathetic imparts digestive & evacuation functions; overly expressed during ibs. Colon tissues do not arouse pain during cutting or burning, but distention evokes severe pain.

Irritable Bowel Syndrome (IBS) in males is unusual.  One of my recent papers, accepted for presentation at the 8th Interdisciplinary Congress on Low Back and Pelvic Pain, in Dubai in October 2013, discusses IBS in 20 youngish extreme sport enthusiasts.  The unifying theme is that they all had sacroiliac joint subluxation via the Occupational Disabilities Guidelines.  They all reported serious pelvic girdle mechanical injury absent fracture.  Most were skateboarders.  My hypothesis is that an hypermobile SIJ impinges the parasympathetic branches of the presacral plexus, stimulating these tracts to the colon.  The parasympathetic nerves of the pelvis activate colon evacuation.
