Table generates matrix, not column

Question

I have several columns. two of them look like the following (one for gamma, one for sigma):

columnA = 
  Column[{γ, 0.1, 0.1, 0.1, 0.1, 0.6, 0.6, 0.6, 0.6, 1.1, 1.1, 1.1, 1.1, 1.6, 1.6, 1.6, 1.6}]

One of them is generated from table:

ColumnC =
  Column[
    Table[
      Limit[f(k, γ, σ), k -> ∞], 
      {γ, {0.1, 0.1, 0.1, 0.1, 0.6, 0.6, 0.6, 0.6, 1.1, 1.1, 1.1, 1.1, 1.6, 1.6, 1.6, 1.6}}, 
      {σ, {0.1, 0.6, 1.1, 1.6, 0.1, 0.6, 1.1, 1.6, 0.1, 0.6, 1.1, 1.6, 0.1, 0.6, 1.1, 1.6}}]]

When ColumnC is generated, it is a 16*16 matrix, though I expected column of 16 values that are limits, which take corresponding values of γ and σ.

In the end, I want to be able to do

Grid[columnA, columnB, columnC]

Answer 1

I think you really want something like

gammas = {0.1, 0.1, 0.6, 0.6};
sigmas = {0.1, 0.6, 0.1, 0.6};
data = 
  MapThread[{#1, #2, Limit[f[k, #1, #2], k -> ∞]} &, {gammas, sigmas}]
Grid[Prepend[data, {"γ", "σ", "Limit"}]]

Answer 2

Here's one approach:

allgammas = {0.1, 0.1, 0.1, 0.1, 0.6, 0.6, 0.6, 0.6, 1.1, 1.1, 1.1, 
   1.1, 1.6, 1.6, 1.6, 1.6};
allsigmas = {0.1, 0.6, 1.1, 1.6, 0.1, 0.6, 1.1, 1.6, 0.1, 0.6, 1.1, 
   1.6, 0.1, 0.6, 1.1, 1.6};
allfs = Limit[f[k, #[[1]], #[[2]]], k -> \[Infinity]] & /@ 
 Transpose[{allgammas, allsigmas}]

This gives you a list of all the f[ ]'s evaluated at the values in the allgammas and allsigma lists. Then you can get your grid as

Grid[Transpose[{allgammas, allsigmas, allfs}]]

Of course you'll need to define f[ ] to have it do anything useful.
