Gets or sets whether the Automatic Filter Row is displayed.
true to show the automatic filter row; otherwise, false. The default is false.
The automatic filter row allows end-users to filter data on the fly, by typing text directly into the row. When an end-user types the text within the row, a filter condition is automatically created, based upon the values entered, and applied to the column.
By default, the auto-filter row is hidden. It can be activated by setting the ShowAutoFilterRow property to true.
