We need to flush this out first. Consider the following:

A  | B  | C  | D  | E
---+----+----+----+----
3  | 1  | 0  | 2  | 4     <== original values
30%| 10%| 0% | 20%| 40%   <== % of total table calc

Now suppose we want to apply the following filter: table calc < 30%

Thus columns A and E are now filtered out. The following is the result:

 B  | C  | D  
----+----+----
 1  | 0  | 2      <== original values
 33%| 0% | 67%    <== % of total table calc

Note the table calc values are changed due to the filter. AND the result does NOT appear to respect the filter; 33% and 67% should be filtered out!

We need a specific use case from the requesting customer before we can proceed.

Another approach:

1. Treat filters with table calculations as special filters such that these filters do NOT actually filter out anything in the pivot table; they only hide what is in the view. Thus in the above example, the result would be that the table calc values remains unchanged from prior to the filter being applied. Only columns A and E are hidden from the view.
2. Also allow table calc filter to be applied on Totals if Totals are being shown. For example, filter out any rows with Totals < 1000.
