numRows(SkewTableau) -- the number of rows in a tableau

Function: numRows
Usage:

numRows T
Inputs:
- T, an instance of the type SkewTableau, a tableau.
Outputs:
- n, an integer, the number of rows in T.

Description

The number of rows is the same as the length of its shapes, excluding trailing $0$'s.

i1 : T = skewTableau(new Partition from {4,3,1,0}, new Partition from {1,1,3,2,0})

         ┌───┬───┬───┐
o1 =     │   │   │   │
         ├───┼───┼───┘
         │   │   │    
         ├───┼───┤

     └───┴───┘        

o1 : SkewTableau

i2 : numRows T

o2 = 4

i3 : (lam,mu) = standardize skewShape T

o3 = (Partition{4, 3, 1, 0}, Partition{1, 1, 3, 2})

o3 : Sequence

i4 : #lam

o4 = 4
