Workbook(class) 由xlwt.Workbook()返回encoding:                 编码方案
add_sheet(sheet_name):    添加sheet
get_sheet(Sheet_name):    选择sheet
save(file_name):          保存Worksheet(class) 由Workbook object相关方法返回 write(rows,colx,cell_value,style):         编辑单元格
row(rowx).write(colx,cell_value,style):    编辑行
flush_row_data():                          减少内存压力，flush之前行不可再修改
col(colx),write(rows,cell_value,style):    编辑列easyxf(function) 创建XFStyle instance，格式控制expression syntax: (<element>:(<attribute> <value>,)+;)+
<element> - <attribute> - <value>:
