Reduce[{-h <= k + 1 <= h, -h <= k <= h}, k]

(h == 1/2 && k == -(1/2)) || (h > 1/2 && -h <= k <= -1 + h)

%[[-1, -1]]

-h <= k <= -1 + h

In the Table, the iterator for k should be {k, -h, h-1}

=============
I am constructing a Table

h=60
hi=60
P1 = Flatten[
    Table[{Pk[k].Fl[l], k + l}, {k, -h, 
      h}, {l, -hi, hi}], 1]
This yields a table with two columns. First column contains vector of order n and column 2 contains an scalar
I want to add conditions to generate the elements in the Table
-h<=k+l<=h. 
I do not know how to do this with the function Table[..] of Mathematica. I am asking for your help.
I do not want rows in my table that do not satisfy the condition.  

Pk[k] is matrix and Fl[l] is a column vector

Thanks in advance
