Hi Arun,
In Quick Filter, we can't able to see any Null Value to restrict upon Measure or Dimension. But if you select "Is Not Null" it will work as you intend. Or if you want to display only the Null / Empty Value rows in table then you can select "Is Null".
eg. This below filter will display the Measure Value which is not null in the Column of Table.
If you want to do Table Level filter on Information, you can goto Table Properties then Uncheck/Check the Check Box which you want to restrict data.
Hope this information helps you for an extent...
