Matrix-type Django admin for two-dimensional data -

suppose have two-dimensional data model:

class a(models.model):     name = models.charfield()     # ... more metadata  class b(models.model):     name = models.charfield()     # ... more metadata  class value(models.model):     = models.foreignkey(a)     b = models.foreignkey(b)     value = models.integerfield() 

so normalized version of matrix of data:

    | a1 | a2 | a3 | a4   -----------------------  b1 | 5  | 9  | 2  | 1  b2 | 8  | 3  | 3  | 8  b3 | 4  | 9  | 5  | 7  b4 | 2  | 6  | 2  | 7 

is there way present matrix in django admin, such can edited in case many values in matrix need updated simultaneously?
