Numbers: Identify and manage filters across tables/sheets
If a filter is added to a table in a Numbers sheet, the Filters on/off toggle is highlighted while the table is in focus.
If a different table is selected while the filter is active, the Filters toggle is greyed. To turn the filter off, the filtered table must be selected to enable the toggle first.
If another sheet is opened, the toggle becomes completely disabled.
When a sheet that has a filter is opened, if the filtered table isn't focused by default, the panel shows no active filters. The table with the filter must be selected first. There are some other behaviours around this that are complex to explain.
The bottom line is that if a table in a Numbers spreadsheet has a filter, the only reliable way to tell is to select that table in the sheet. Otherwise, it's likely there's no indication that anything is filtered.
Is there a way to find out which tables have filters, or to turn off all filters, without having to visit each sheet and focus each table one by one with the filters panel open?
