Hi I’m new here,

I have one question regarding UiPath DataTable.

In UiPath, I want to add a new column to an existing DataTable without using the “Add Data Column” activity.

Can anyone help me with the proper solution?

Thanks

Hi,

You can try this:
Use an Assign activity.
NewColumn → yourdatatblename.Columns.Add(“NewColumnName”, GetType(String))

Variable type: NewColumn → System.Data.DataTable

Thanks

Hi @Ss_RPA
Welcome to the Community
Try this

Make sure your DataTable is already created
Example name: dtData
Drag and drop assign activity
Pass this dtData.Columns.Add(“NewColumn”, GetType(String))
If you want give the new colume value for all rows then use for each row

CurrentRow(“NewColumn”) = “Done”
Continue with next steps

Please let me know if you still face the issue and if solution works for you please mark as solved
Thanks & Happy Automations

Hi @Ss_RPA ,

You can add a column directly using an Assign activity with this line:

dt.Columns.Add(“NewColumnName”, GetType(String))

This adds a new column to the existing DataTable without using the Add Data Column activity.

@Ss_RPA,

Any reason for not using the Add Data Column activity?
