openpyxl错误：'str'对象没有属性'BLACK'

Question

我想使用pythons OPENPYXL模块在excel电子表格上设置样式。我一直想出这个错误：

'str' object has no attribute 'BLACK'

基本上，我的代码读取从.xlsx文件已知值的列表，并把它们放入一个Python列表。我使用该列表来比较访问表中列中的值，以确保每个单元格中的值与已知值相比是正确的。

当我尝试使用openpyxl设置样式时，脚本被吹掉了。出于某种原因，上面的错误出现了。奇怪的是，我甚至没有在任何地方使用BLACK，并且当我尝试设置填充时似乎错误。在脚本的SearchCursor部分中，它遍历每一行。第二遍，剧本爆发了。我有一种感觉，它想覆盖一些东西，但我无法弄清楚什么。

TableList = [] 
for row in arcpy.SearchCursor(r"Z:\Domains\Domains.xlsx\DOMAINS$"): 
    TableList.append(row.Code) 


# Create workbook for report. Openpyxl

        x += 1 
        print 'first' 
       elif len(row.INCLUSION_TYPE) not in range(2,5):

        new_sheet.cell(None,x,fieldKey).value = row.OBJECTID       
        x += 1 
        print 'third' 

       print x 

Answer 1

问题是行中存在定义颜色的问题。只需将颜色分配给style.fill.start_color.index即可。例如：

new_sheet.cell(None,x,fieldKey).style.fill.start_color.index = 'FF808000' 

代替：

new_sheet.cell(None,x,fieldKey).style.fill.start_color.index = openpyxl.style.Color = 'FF808000'
