I would like to create table of summation expressions, which are not evaluated, but summation limits are substituted.

I can't accomplish this so far.

If I write

enter image description here

I get summation expanded.

If I write:

enter image description here

I get "Hold" word displayed and summation limits not substituted.

If I write:

enter image description here

I get limits not substituted.

    $\begingroup$ Providing code would be a good idea nevertheless. $\endgroup$

    $\begingroup$ Use With[{n=n},... to inject into held expressions. $\endgroup$
