Question

我已经使用了一段时间的熊猫，我认为它是一个很棒的工具。我制作了一个程序，用来从用户收集的一些数据中生成一些excel文件。最终用户已经测试并使用它6个月;它永远不会失败，直到昨天，它生成了一个dagamaged excel文件。当我用文本编辑器打开它时，它完全是空白的。生成此文件的代码是：

        escritor = pandas.ExcelWriter(direccion, engine='xlsxwriter')
        listaTotal.to_excel(escritor, index = False)
        escritor.save()

和

        escritor = pandas.ExcelWriter(direccion + '.xlsx', engine='xlsxwriter')
        self.listaFact.to_excel(escritor, index = False, startrow = 1, startcol = 0, sheet_name = 'Hoja1')
        escritor.save()

第二个代码片段也为＆＃39; xlsxwriter＆＃39;使用了一些格式选项，这里有一个示例：

        format = workbook.add_format()
        format.set_font_size(9)
        format.set_font_name('Sans Serif 12cpi')
        format.set_border()
        format.set_text_wrap()

这个错误发生了两次;大约1个月前和昨天。我无法复制错误，我也不知道发生了什么。并且跟踪在这里，它显示程序读取文件时的问题，但此文件是由之前发布的代码生成的：
