 ### Advanced Filters {#advanced}
-
 To access the Advanced Filters the user may click/tap the "Filters" button found in the table controls area. When activated, the button transforms into a tab and displays the available filters in a 'drawer' which opens between the table controls and the table data. The available filters are determined by the columns present in the table; therefore, if the user customizes the column visibility of the table to show some columns and hide others, the corresponding filters for these columns will display or hide in the filter 'drawer'.
