Main.xaml (12.8 KB)TestingDataTable_Merge.xlsx (10.3 KB)

I am practising my skills on datatable manipulation.
And I dont seem to understand how to use the add data row function.

Please take a look at the workflow and let me know why the above said error occur?

Thanks alot people!

Yeah Exactly!
So what I am missing is the “CopyToDataTable” command.

Few follow up questions below:

  1. So the command basically combined array of datarows to form a datatable?

  2. Regarding my original workflow, I was wondering what’s the correct way to add a whole line of data row to a new data table?
    For example, adding a data row to a new data table.

  3. The filter data table function from Uipath is not working 100% of the time, is that normal?

Thanks for the quick reply PrankurJoshi! Appreciated. Sorry for having more questions. Thank you.

Regards
Tower

Here is same thing with Add Data Row

Main (6).xaml (12.6 KB)

Ans3. Filter data table works just fine, if not check the conditions.
Ans2. You are in a loop and copying the same row on what you are working that was the error
Ans1. Returns a Datatable that contains copies of Datarow objects

Thanks a lot Joshi!
Last question, is there a way that I could add those header back in the final output with this method?

Thanks for the quick reply! :slight_smile:

Oh I thought after the dt.selet command, the header was lost…

Sorry about that. Thanks!
