Sorting datatable

Question

Hi all,

Using Oledb, I've imported an excel sheet into a datatable.

I now need to sort this by "number" and then "date". I know how to do this with a datagridview, but I want the data held in the table to be permanently sorted, not just a view of it.

Could someone give me a breakdown of the step I need to follow to achieve this?

Thanks in advance.
