Does this mean we can consider rows and columns separately or for any cell we have to consider both the columns and rows?

For example, do w,a,k,x,z all need to be unique or just (w,x,z), and (w,a,k)

Elements in each row and column have to be unique. If you consider the row and column containing w, then (w, x, z) and (w, a, k) have to be unique. w, a, k, x and z may or may not be unique. Its similar to Sudoku!
