Until fairly recently, you could filter Google Analytics tables only by primary dimension value.
For example, you could easily filter the Pages report to display only Page values that contained a text string such as “mydirectory” or “thank-you-page”, but you could not filter by metrics values such as pageviews or bounce rate.
The new Advanced Table Filter provides much greater flexibility and allows you to filter by primary dimension value and/or any combination of table metrics.
One possible use would be to filter out anomalies before exporting or presenting a report for a broader audience. In the screen shot provided, page values that had 5 pages or fewer during the time period selected will be excluded so as not to distract from the report’s more significant data.
