            Source,
            (sourceOuter,col) =>

                    TranslationList,
                    sourceOuter,
                    (sourceInner,translationCouple) =>
                        Table.TransformColumns(
                            sourceInner,
                            {col, 
                             each Replacer.ReplaceText(_,translationCouple{0},translationCouple{1})}
                        )
