Как добавить новый лист в существующий файл xls

Question

Мне нужно добавить новый лист с различными методами и заголовками в пределах одной и той же книги. Я могу добавить новый лист, но как добавить отдельные методы и заголовки для второго листа? Сейчас оба листа являются дубликатными копиями. В принципе, как бы добавить другие данные на оба листа. Любая помощь будет оценена, и я всегда принимаю ответы, а также голосование.
