问题描述
我想从上一行获取一个值.
I want to get a value from the previous row.
我尝试了这篇文章:
Table.AddColumn(#"Added index", "custom column", each {[Index]-1}[column name])但是它抛出了这个错误:
But it throws this error:
Cannot use field access fot type List请帮助,我在做什么错了?
Please help, what am I doing wrong?
推荐答案出现错误是因为{[Index]-1}之前没有任何内容是列表值,但您希望使用以下语法索引到表的行中: c1>
The error comes because {[Index]-1} without anything before it is a list value, but instead you want to index into a row of a table with this syntax: MyTable{index}
看起来像:
= Table.AddColumn(#"Added index", "custom column", each #"Added index"{[Index]-1}[My Column])更多推荐
