Conditional Formatting xlwt

阅读更多关于 Conditional Formatting xlwt

问题 I have seen some posts that say you can NOT perform conditional formatting using xlwt , but they were rather old. I was curious if this has evolved? I have been searching for about half a day now. Furthermore, if I con't write it directly from xlwt , can I create an .xls file containing a single cell with the conditional format I want and have xlrd read that format and paste it into the sheet I aim to produce then using xlwt ? 回答1: xlrd and xlwt still don't support conditional formatting .

python操作Excel(xlwt、xlrd、xlutils)

阅读更多关于 python操作Excel(xlwt、xlrd、xlutils)

简介 python中通过xlwt、xlrd和xlutils三个模块操作xls文件。这三个模块的区别如下： xlwt：xlwt用于在内存中生成一个xlsx/xls对象，增加表格数据，并把内存中的xls对象保存为本地磁盘xls文件。 xlrd：xlrd用于把本地xls文件加载到内存中，可以读取xls文件的表格数据，查询xls文件的相关信息。 xlutils：xlutils模块是xlrd和xlwt之间的桥梁，读取xls文件可以使用xlrd，新建创建文件可以使用xlwt，而修改文件则使用xlutils；可以使用xlutils模块中的copy模块拷贝一份通过xlrd读取到内存中的xls对象，就可以在拷贝对象上像xlwt中那样修改xls表格的内容，并保存到本地。除此之外，还有一些其他的模块也可以用于操作excel文件，如xlwings、openyxl、xlsxwriter、win32com和pandas库三个模块的安装方法还是使用pip指令进行安装，具体如下： xlwt： pip install xlwt xlrd： pip install xlrd xlutils： pip install xluntils 使用示例 1、创建excel文件——xlwt的用法 # 创建一个excel对象 excel = xlwt .

问题 At fisrt, I use xlsxwriter to write a simple formula in one cell and close the *.xlsx file. Then I try to read the value of the cell but only read '0' from the cell using xlrd at the same program. If I read some fixed values (like string or constant number) in a cell, it works well. If I create a formula cell manually in a *.xlsx file, the xlrd can also get the value of the formula. It seems that I cannot read the value of formula cell only when I write a forumla to *.xlsx and then read it in
