如何计算xlsxwriter中Excel文档中的行数

does anyone know how to count the number of rows on an Excel worksheet using xlsxwriter? I have looked for a method similar to XLRD's worksheet.nrows in xlsxwriter but have not been able to find one. I had orginally tried to use both xlsxwriter and xlrd in a script but I have errors due to what I think is a problem with both xlsxwriter and xlrd trying to open the same file at the same time. I can attach the code if that would help. Thank you very much in advance!does anyone know how to count the number of row
