1) they did not fight a formation (as Greeks, Romans or Sumerians did) they fought in groups or bands, hence already there is the creation of a proper wall difficult at best (since you need a structured command and not just a mate that has a shield, 2 people do NOT constitute a shield wall, just as much as 2 bricks do not constitute a wall).
2) War and warfare definitely played an important role in ancient Celtic society. The nobility most probably was a warrior elite that spent considerable time training with weapons. For them, fighting and raiding were quite common occurrences. The client landowners most probably were also required to fight if and when the need arose, both to defend their own land and to attack enemies. Since they were involved in the production-cycle, they however did not have as much or any training in actual military tactics.
3) A Celtic warrior’s basic equipment consisted of a set of one to four spears. One was a 1.8 meters long fighting spear called a "lancea" that sometimes had very large spearheads of up to 50 centimetres in length these were used to dismount horses and to stop a cavalry charge. The others were short throwing spears called "gaesum" with relatively small, normally shorter than 10 centimetres long spearheads compatible to a light Roman pilum and use for throwing at the enemy before a charge. A warrior also had a large—about 1.2 meter high and 0.5 meters wide—leather-covered, wooden shield with a metal shield-boss. This was likely to have been decorated with painting and sometimes metal ornamentation. With this basic equipment, the average warrior usually wore his everyday clothing consisting of trousers, a shirt, and a mantle.
So it is fair to assume that shield walls was not something Celtic tribes did, they did however adapt the Roman tactics and might in AD has used some shield tactics.
