1)When you are working with data tables containing information that you received from another person, you may want to prune the amount of data in the table by deleting rows in particular.
2)To begin with, the Filter feature is only accessible in File Explorer\'s Details view. The reason for this is that the Filter feature actually lives in the column headers that display at the top of the File List pane when you\'re using the Details View.For example, the Documents Library displays the Name, Date modified.
3)When you place your mouse pointer over any one of the column headings, you\'ll notice that a drop-down arrow appears on the right side of the heading. This drop-down arrow provides you with access to the Filter feature, which manifests itself as a menu that displays the Filter options that are appropriate to the heading type. For example, the Filter menu on the Name heading displays Filter options that show groups of numbers and letters.
3)Selecting one or more of the check boxes enables that filter.
By using these option you can implement the optional delete option for a particular column as u said lastname.
