You can order or arrange the order of your records in your data table by a particular column by clicking on the arrow icons 
of the column you want to sort by.
The header of the column you have selected to sort by will highlight in a darker grey color to indicate the column you are ordering your list by.
Clicking the order option once will order your records by that column in ascending order and clicking it again will reorder the records by that column in descending order.
