SheetSet.AddSheet的语法是什么？

elite

Dim sheetset As New sheetset

Set sheet1 = sheetset.AddSheet(categoryX2, _
                                  "Sheet 1", _
                                  "This is sheet1", _
                                  "Sheet 1", _
                                  resourcePath + "\" + "Sheet 1.dwg")

AddSheet这个方法我在帮助文档中未找到，请问它的AddSheet语法格式。
