sortColumnsTableau(y)
This method sorts the columns of the tableau and retrieves the sign of the associated permutation
i1 : p = new Partition from {2,2,1} o1 = Partition{2, 2, 1} o1 : Partition
i2 : y = youngTableau(p,{0,1,4,3,2}) o2 = | 0 1 | | 4 3 | | 2 | o2 : YoungTableau
i3 : sortColumnsTableau y o3 = -1
i4 : y o4 = | 0 1 | | 2 3 | | 4 | o4 : YoungTableau
