filter functionality in data table with dynamic columns

[veekay1357]

Hi,
I am trying to implement filter functionality in a data table which is having dynamic set of columns. Prime faces do a filtering for each and every column and no matter filter value is provided or not and if no value provided , filtering is done with empty string. This get wrong if column data type is NUMBER or DATE. How could we overcome the default filter action by Primefaces for those columns which are not provided with any filter values?
