[Mengdi_Wei]

Hi all,
I found a way to solve my “append a new column” question. Thank you all for helping me.
Now, I meet a new question about filter data table, I wonder if anyone of you can help me with that.

Problem on filter data table activity

Hi All, I meet a problem when using the filter data table activity. I want to filter out the rows that only “AbsoluteDifference” > 2, but my workflow does not work. There is nothing shown on the output folder - validated Excel - sheet 2. I wonder if you can help me with that. I put my xaml and input excel here. Thank you very much!
