ValueError: The name 'Subject identification [Individual/Pool]' already exists in the column collection. Parameter name: value

Question

下面的代码返回错误：我没有发现这个错误 googlying..

import datetime
from Spotfire.Dxp.Data import IndexSet
from Spotfire.Dxp.Data import RowSelection
from Spotfire.Dxp.Data import IndexSet, DataValueCursor, RowSelection
from Spotfire.Dxp.Data.DataType import DateTime

dictTable = Document.Data.Tables['Column renaming mapping']
dictionary = dict()
key = 0
value = 0
colNum = 0
cursorKeys = DataValueCursor.CreateFormatted(dictTable.Columns['PDW short name'])
cursorValues = DataValueCursor.CreateFormatted(dictTable.Columns['PDW long name'])
rowCount = dictTable.RowCount
rowsToInclude = IndexSet(rowCount,True)

for row in dictTable.GetRows(rowsToInclude,cursorKeys,cursorValues):

    rowIndex = row.Index
    key =   cursorKeys.CurrentValue
    print key
    val    = cursorValues.CurrentValue
    print val
    dictionary[key] = val

for table in Document.Data.Tables:

    for col in table.Columns:

        if col.Name in dictionary:
            col.Name = dictionary[key]

我当然做错了。我的目标是迭代所有 tables 并修改某些列的命名。我希望根据 table 我调用 discTable.

修改它们

根据代码生成的内容添加完整错误和打印结果。

Answer 1

如果您尝试将列重命名为 table 中已使用的列（给定 table 中的 2 列不能重名），则会出现此错误。我建议弄清楚哪个 table 导致错误并仔细检查是否还没有名为 'Subject identification [Individual/Pool]'

的列

谢谢，亚采克！
