A data table is often where people spend most of their time, even when the dashboard gets more attention. Clear headers, sensible number formatting, and visible filter state can make routine work much easier. On a smaller screen, too many fixed columns can make the whole table awkward.
If you could improve only three things in a dense analytics table, what would you choose? Think about keyboard navigation, comparing values, exporting data, and recovering from an accidental filter. Concrete examples of frustrating table behavior are welcome.
