How to add a new column to a data table to reflect rows in current filtering?

2. In the action control dialog, click on the “Actions” button. Enter the display text.
3. In the “Available actions” section, click on the plus sign before “Functions” to view the full list of functions.
4. Select “Mark Filtered Rows”. Click “Add”.
5. Select “Filter to Marked Rows”. Click “Add”.
6. Select “Unmark Marked Rows”. Click “Add”.
7. The order of the above three actions cannot be changed. Please make sure “Mark Filtered Rows” is the first function and “Unmark Marked Rows” is the last function.
8. Click “OK”. Save the text area edit.
9. Now, change the filters and click on the action button you just added.
10. You will notice that a new column will be added. The name of the column is “Filtered to at [time]” with values “Yes” and “No”. Rows with “Yes” are those you have filtered to. Rows with “No” are those you have filtered out.
11. If you change your filter, click on the action control button again to update the column.
