First I am handling the CellFormating event, then with the first if statement I am making sure it is thrown for a specific column. The second if statement checks the type of the element and if it is a cell, we can set its ContentAlingment property. If you also want to format the column heading you can omit the second if statement.
In the attached demo you can find the entire logic I use.
I hope this helps. Should you have any other questions do not hesitate to ask.
