|available| already contains |allocAuto|, if |numAuto| (a few lines up).

Maybe we should never enter both blocks, so that the code should better read:

    if (available > 0 && (numAuto || numAutoEmptyCellsOnly)) {
        available += allocAuto;
        if (numAuto) {
            distributeWidthToColumns<float, Auto, NonEmptyCells, InitialWidth,
StartToEnd>(available, totalAuto);
        } else {
            unsigned total = numAutoEmptyCellsOnly;
            distributeWidthToColumns<unsigned, Auto, EmptyCells, InitialWidth,
StartToEnd>(available, total);
        }
    }

         distributeWidthToColumns<unsigned, Auto, EmptyCells, InitialWidth, StartToEnd>(available, total);
     }
