The lambda expression is looking fairly complicated so I wonder if it could be made simpler or if there's any other algorithm I should've used to put a separator between the elements?

How about,

std::size_t i = 0;

//...
(
    if_(var(i)++) [ var(outputText) += constant(fieldSeparator) ],
    var(outputText) += bind(&Column::getColumnText,_1)
)
