Thanks for your quick response.
I however do not understand it entirely.
Maybe it will help me if I refer to the example:
We want to remove all rows that contain “PV”.
We need to assign data.Select("[Status]=‘PV’") to data_to_del
Instead of selecting the column named [Status], I want to select the second column (with index 1).
What does the zero of Columns represent, and does Columnname means the header?
And why is it equal to 1?
Can you elaborate on it a bit?
