[英]How can I get the externalname of a column using IronPython in Spotfire?
Currently I need to change the name of a column depending on specific criteria but to do that I'd like to refer to that column by its ExternalName rather than its name. 当前,我需要根据特定条件来更改列的名称,但是要做到这一点,我想通过它的ExternalName而不是它的名称来引用该列。
aColumn = Document.ActiveDataTableReference.Columns["I_id"].Name
unfortunately this doesn't work. 不幸的是,这行不通。
aColumn = Document.ActiveDataTableReference.Columns["I_id"].ExternalName
you're very close! 你很亲密!
ExternalName
isn't a property of the DataColumn
object , which is, I suppose you've figured out, why your approach isn't working. ExternalName
不是DataColumn
对象的属性,我想您已经知道了为什么您的方法不起作用。
in fact, ExternalName
is an item represented by the DataColumnProperties.DefaultProperties
class . 实际上,
ExternalName
是由DataColumnProperties.DefaultProperties
类表示的项。 you would actually access this as if it were a custom-defined Column Property like so: 您实际上将访问它,就像它是一个自定义的Column属性一样:
col_ext_name = Document.ActiveDataTableReference.Columns["I_id"].Properties["ExternalName"]
print(col_ext_name)
>> index_id
