        (x) => x[i] < List.Count(data),
        (x) => [i = x[i] + 1, row = data{i}, first_five = List.FirstN(row, 5), replace = first_five = x[first_five]],
        (x) => if x[replace] then nulls & List.Skip(x[row], 5) else x[row]
    ), 
    tbl = Table.FromRows(gen, Table.ColumnNames(merged_result))
