Sorry, unable to do so because of client confidentiality requirement.
Perhaps you could provide the steps on how to copy entire columns from one table to another, looping column by column? Also I do not have Join Data Tables on my version of UiPath
You can see the sample workflow - It should solve your problem - you can improve as well by using loops for multiple columns instead of add one by one.
Let me know if you face any issue to understand the sample.CopyDataColumns.xaml (12.0 KB)
Is it possible to just use the DataTable.Columns.Add and specify a DataColumn object as the input parameter? Instead of passing column name and data type
Initially the destination table is blank and has no data, so I get error when copying into it “There is no row at position 0”… how do I fix this?
If the 1st Datatable is empty and you want to add columns from another Datatable with data then you have to add rows to your 1st DT with\without values.
