我需要迭代每一行，将项添加到字典中，进行一些排序，然后将结果吐出到我需要通过脚本动态创建的数据表中。
我无法再访问此文章，是否有人有代码可以执行与此类似的操作？

在一些帮助下解决了这个问题。
您必须创建.Net DataSet和DataTable，在内存中添加行，处理表并从数据创建制表符分隔的字符串，然后使用Stream创建Spotfire TextDataSource ...然后您可以创建数据Spotfire中的表使用内存文本数据源（而不是物理文本文件）。
此代码中还有其他与我试图解决的问题相关的内容，但它可能对其他人有用。

而不是
for row in dataTable.Rows:
textData += row["Registration ID"] + "\t" + str(row["Date 1"]) + "\t" + str(row["Date 2"]) + "\t" + str(row["Date 3"]) + "\t" + str(row["Date 4"]) + "\t" + str(row["Date 5"]) + "\t" + row["Sequence"] + "\r\n"
我用过
output = cStringIO.StringIO()
for row in dataTable.Rows:
output.write(row["Registration ID"] + "\t" + str(row["Date 1"]) + "\t" + str(row["Date 2"]) + "\t" + str(row["Date 3"]) + "\t" + str(row["Date 4"]) + "\t" + str(row["Date 5"]) + "\t" + row["Sequence"] + "\r\n")
性能大幅提升。
